>> hello, i'm barbara serra. coming up in the next 60 minutes. egypt declares it is in a state of war. 17 soldiers were among 100 people killed in battles north of sinai. the greek prime minister urges it's cash-strapped people

to vote no in the referendum. >> the u.s. and cuba resume full diplomatic relations for the first time in 54 years. plus... >> the amount of damage they can do and i've seen it firsthand is quite amazeing. >> theamaze wreaking havoc on australia's great barrier reef. can it be stopped. >> we have more in sport including defending champion djokovic reaches the third round of wimbledon as the temperatures soar. >> thank you for joining us. there have been a wave of attacks in sinai peninsula. thea group calling itself province of sinai. it's one of the largest

coordinated assaults. there have been conflicting reports, but 17 soldiers and 100 attackers have been killed. in response to the fighting egypt's prime minister said that his country was in a state of war. and in a separate development secure officials say nine members of the banned muslim brother has been killed. one of the dead is a prominent muslim brotherhood lawyer. first we have reports on a violent day in the sinai peninsula. >> these pictures show an air force strike on the egyptian town of rafa. they have put the area in lockdown following a deadly attack on its soldiers. in a statement on state television judgment's military leadership said that 17 soldiers had been killed and the army had inflicted heavy casualtyies.

>> in the north of sinai hunted down and this was the hide out of those operatives. killing not less than hundred terrorist operators and wounding dozens of them. >> it comes a day after egypt buried it's public prosecutor who was killed in a car bomb attack in die row. president el-sisi has ordered his cabinet to change current laws to face what he called terrorism. since the two years ago violence in sinai has increased in 2014 the group became known as province of sinai and swore allegiance to the islamic state in iraq and the levant. it carried out more attacks and proved to be one of egypt's biggest threats. egyptian military intensified its security campaign carrying out attacks against what it says

were terrorist hide outside. hundreds of families have been forced out of their homes. i sinai province is not new. they claim of neglect, under development, unemployment and poverty. many hearsay they have been treated as second class citizens by consecutive egyptian governments. >> recent increase in violence in egypt began with the killing of the state prosecutor on monday. that's prompted a government crackdown. the muslim brother said that nine members have been killed by egyptian security forces outside of capital of cairo. one of the dead is a prominent

prominent muslim brotherhood lawyer. we smoke to a muslim brotherhood spokesman, and he gave this description of the police raid in cairo. >> there was a meeting on a group of persons of those responsible for supporting the family of victims. they were in an meeting in the area. they were all assassinateed in cold blood. this failed presence after killing and detaining many is now murdering those supporting the families of those victims and we were just merely supporting bereaved mothers children and widows of the victims. they blamed the innocent for the killing. among the victims was engineer abdul ebra ibrahim. and the adviser to the detainees saying both along with the

fellow committee members were murdered. they were not armed. nor were they engaged with any fight of their assassinate their their atheir assassin. the regime thugs stormed the palace and murdered them without warning. >> al jazeera's egyptian affairs joins us live now from doha. a lot of developments we've seen in egypt really today but over the past few days just clarify for us the link between the increased violence that we're seeing in the sinai and the crackdown that we're seeing on the muslim brotherhood. >> yes, of course, the development not only in sinai but in different places in egypt. today actually this huge attack maybe the most huge attacks

during two years in sinai and also there is some other weekend see explosions in many other cities in egypt especially in, for example some electricity cables under electricity station. to stop because of this bomb explosion, and also there is many other explosions in egypt and it's a little small but we can say that the violence is spreading in different areas in egypt. it's a bloody day it's a day of huge tension government, as you may know, is in continuous meeting, prime minister ibrahim after the meeting today, which is already held up outside of

the cabinet head quarter in the police academy outside of the capital because of this security tension. the government approveed already we can see terrorism the number of killing people in the muslim brotherhood is increasing now to 13. not only are the sources right now, some information from the families of the victims are saying that that the leaders of the muslim brotherhood was in under arrest from the morning of the day and day are killed after arresting.

they're saying, of course, that they are saying that we have clashes with the police. but the families of many of the families of those leaders talk to us and are saying that they are already told by the police in the morning that they are under arrest, and they were told after that in the evening that they are killed, and they have to go to the hospital to take their belongings. there is a huge gap between what the government is saying and and they're saying that they killed more than 70 soldiers from the army, and there is we

can see a statement only 17 soldiers were killed, and the army killed about hundred from the militant group. >> forgive me for interrupting, you're mentioning the statements. we've seen tensions for a long time in the sinai between the muslim brotherhood and the government but it's the words that we're hearing. the government is saying that they're in a state of war. they're talking about purifying the semi peninsula and the muslim brotherhood as well. they said this would an turning point that could lead to reaction quote the oppressed. this kind of language escalated even further. what are we seeing in the tense relations any way? actually observers and they are saying that the war is again the

political parts, not towards the target, which are the militants or the militant groups. they attack everybody today as we can see political opposition leaders. they are liberal groups they're saying that the war against terrorism is towards a wrong target, a militant group. for example now just hours before assassination of the public persecutor that they are

killed already three judges, and that they are going already facing the army and the police although the attacks are towards the muslim brotherhood and the opposition parties and the groups. they are saying that it's toward the wrong target. it's not enough to solve the problem in egypt, it's a political problem a political crisis and political solution not only security solution. they didn't see any link up towards this muslim brotherhood and towards the probes in different government the

brotherhood and they issued a statement that they didn't have any relation with the assassination, and they're trying to seek a link between liberal and islamic such as muslim brotherhood. >> head of egyptian affairs joining us, thank you. let's go to greece where the prime minister has reaffirmed that the ref run that the ref runreferendum is know will be

held sunday and that they want to vote know. in a letter he told lenders that they could accept bail out offer if conditions were changed. they asked for a $1 billion loan to cover restatement. he's under political pressure to end the stand off as they find that supplies of bank notes are now running low. here is barnaby phillips. >> this man has a difficult job telling pensioners they have to weight. they're allowed into the bank one by one to collect money. they've been here for hours. these scenes are not helpful. he's telling greeks their money is safe, and they should vote no to strength greece' position in negotiations. >> no does not mean a split division but a return to values.

no means strong pressure for economic viable agreement that will give solutions to the dead. >> the greeks prime minister has made a new offer with concessions, but it seems that many of europe's most powerful applications are now giving him the cold shoulder. >> i always kept to what we agreed on, what our rules are what we agree and in europe and what the national roles on. if everyone has done the same greece would not be in such a desperate situation. looking for a culprit outside of greece may be helpful in greece but it has nothing to do with reality. >> while europe leaders bicker what do tourists think? we found them trekking up to the aged acropolis. some oblivious to the financial crisis, some taking it in their stride. >> i heard that the banks may be closed so i brought cash from

home basically. >> now we'll carry on as natural. >> for the greeks themselves the situation is much more worrying. they can't escape their country's financial crisis. and yet for all the tensions and disagreements in this country the vast majority of greeks have dealt with the situation with great calm and patience. >> lela gives league advice to bankrupt greeks. 150,000 have declare bankruptcy in the past five years. but what can she possibly tell them now. >> even as lawyers we're afraid about what will happen next. there is a lot of insecurity uncertainty at the moment. we'll wait and see and we'll have a referendum at the end of the week. maybe some things will happen. maybe not. we'll see. >> some how amidst all this the greeks have to make a momentous

decision. >> it increasingly appears that greece's creditors have run out of patience. the international monetary fund said that the current situation is confused. >> we have received so many latest offers which themselves have been validated changed amended over the course of the last few days that it's quite uncertain where the latest proposals stands. i think that in a major decision was made last friday to interrupt the negotiations on the part of greece when they launch a referendum. there is a democratic process and that should result in hopefully more clarity. >> more clarity wouldn't we all

like that. we go to a greek journalist and analyst here in london. thank you for being with us. it's been a very busy week. it's obviously been an intense few months for the greeks people. do you think that the scenes we've been seeing for example in barnaby phillips report, people queuing at the banks and not being able to cash in, do you think that will scare the greek people to perhaps vote yes when it comes to the ref referendum on sunday? >> certainly. most likely they're going to vote for yes. let me tell you that an our hour before coming to studio, there was a good friend of mine who was really scared what will

happen if he is going to lose all of his money because it is in the greek base. he is a hard working family, a family of two kids, and he does not know what is going to happen. it doesn't matter how other people of feel, whatever,. >> it's quite interesting watching it from the outside. you you've been covering this cries from northerncovering this crisis from northern europe. how has it been for you covering this crisis from outside of your own country. >> sometimes i understand much better what the europeans want to say to the greek people, and then on the other hand at other times i understand why the greeks are feeling how they feel right now. they're so frustrateing.

we have kids who go to school without breakfast. we have many unemployed people. salaryies have been cut significantly. but on the other hand i understand why my best friend is complaining saying why we need to pay-- >> they're not even in europe. >> yes. >> it's interesting that greece is being used as an example the fear is from all these electorates will go. what do you think would happen if there was a ref run dumb, which we think there will be, and the vote is yes, do you think its possible for tsipras to remain in this position?

>> no, definitely not. it was very clear that he said very clearly he would resign if the people vote yes to the referendum. it makes sense. if. >> briefly, if there is a yes vote in the bail out plan can things really go back to how they were a few months ago or do you think things have changed? >> i don't think things have changed. we need time to go back to the normal situation. >> well, i'm sure we'll be discussing this soon. thank you. >> thank you. >> well still lots more to come on the news hour. calls for help as the u.n. says 21 million people need aid, and yemen raises their level of alert to the highest.

and on the verge of history we look at the women's u.s. team showdown against japan. >> after a half century the u.s. and cuba have cemented their new era of diplomacy. the two nations are reopening their emabout as is friday havana. both sides are ready to move forward as well as. >> a letter to havana. washington restores its ties to the island nation an after more than 50 years. >> on cuban state television a presenter reads a letter from the president raul castro to u.s. president barack obama

confirming the same. that on july 20th its embassy will be open for business. >> this is an historic step forward to normalize relations with the government and people and begin our new chapter in the americas. >> in the short term reestablishing ties will increase business and travel between the two countries. but the normalization will take longer. cuba wants the military base at guantanamo guantanamo bay returned to its control. something that the u.s. opposes. and the u.s. trade embargo cannot be lifted without an act of congress, something that the president will find difficult to achieve. >> you there are those who want to turn back the clock but it's long pastime to realize that this approach does not work. it has not worked for 50 years.

it only makes life worse for the cuban people. so i would ask congress to listen to cuban people, listen to the american people. >> the move to restore ties between havana and washington have been years in the making. but there are many who object. senator marco rubio, a cuban american, is threatening to block the nomination of any ambassador to the island. that means little to people who are lining up for visas in havana. they're focused on what this means to them. >> what joy including today it's five times that i've come to this embassy. i think this will be better yet. >> we've been in the situation for 56 years. and i think this will benefit the country in certain respects. i think it benefits those of us who want to see our families and children who are there in the u.s. >> a turning point in diplomacy and perhaps in the lives of millions on both sides of the straits of florida.

roslind jordan, washington, d.c. >> let's go to washington, d.c. sir, thank you for joining us here on al jazeera. we were just listening to roslind jordan's report. she mentioned some of the stumbleing blocks that remain. the issue of guantanamo bay. is it perhaps pre- premature to start opening embassy when a lot of those stumbling blocks are not resolved? >> the opening of embassies and the restoration of diplomatic relations is the first critical key part in trying to deal with some of these outstanding issues. and so today is an historic day, and we're looking forward to moving forward in the relationship. >> the republicans are openly said that they're going to block funds for it. they vowed to do that.

>> the embassy can be opened by order of the president, and it will be. and at some point this summer secretary kerry intends to travel down there and hold a formformal ceremony marking that. . the embassy can be opened, and we can start to have a restoration now of diplomatic relations with cuba. >> you mentioned naming the ambassador, but senator marco rubio the florida senator who is a candidate for president i

said he would block any nominations. you must concede that a lot of main stumbling blocks are far from being resolved. >> well, look, there are still issues that we don't see eye to eye on with cuban authorities and the cuban government. there is no mistake about that. but you're not going to get resolution on issues like human rights and on freedom of the press without being able to engage and talk frankly and openly. there are a lot of things good about this policy shift but one of the good things about it is that it gives our diplomats an opportunity to engage more with cuban people and the cuban government on these kinds of issues. for 50 years there was no engagement, and there certainly wasn't any movement on any of these issues. this is an important first step to allow for that openness, allow the dialogue and that's the way forward on this. >> now that we have a date for the embassy and it has taken more than six months to get to

that. one of the problems there is knowing the limitations were going for diplomats on either side. do we have clarity? what limitations will there be on both american and cuban diplomats? >> well, we're comfortable that those kinds of arrangements have been established now in this agreement, and we're comfortable that our diplomats will be able to move about the country and to engage the cuban people at all levels. it will be a like situation here in the united states. again, i think both sides are comfortable. >> u.s. state spokes spokesperson from state department, thank you for joining puts less go to lucia newman. i know you've been listening to

that interview, and you've been following the cuban-u.s. relation force very long time. anything that stood out to you from what we heard from the state department spokesperson today? >> what i really notice is that the united states the president and state department emphasize continually open that they're opening up a relation with the cuban government and less than theand--with the cuban people, and less with the cuban government. and it is very clear that there is a lot of distrust. the words were very measured. they said they would be renewing diplomatic ties based on both of their respect for the united nations and vienna convention, which called for the respect for sovereignty and self determination and resolution of conflicts in peaceful means. they're really saying very

different things. but at the end of the day the united states government and we just heard from our state department spokesman is that they're going to go ahead with it no matter how much resistence there is on the part of many republicans. that's something very interesting. >> lucia symbolically when it comes to ordinary people and psychologically for them what impact will it have for them to have a building up with the american flag and one with the cuban flag in washington, d.c.? >> cubans have been going past that very same building more than a half century ago. earth time they go by they'll be taking a double turn. people are in disbelief that this is happening. they said it would never happen within their lifetime. anybody who was warned less warn born less than 53 years ago grew

up with this all their life. this is a very big deal and them hope it will facilitate more into action with business leaders of the united states eventually, and basically help have a much more normal peaceful coexistence with the united states last. >> lucia always great to get your analysis. our latin american editor. thank you. much more ahead on the news hour including turkish tensions fear that syria's war could inflame old problems along the border. also talks inch close for a final deal for iran's nuclear future.

>> welcome back. a reminder of the top stories on al jazeera. egypt's prime minister said that the country is at war after fighters have launched a series of attacks and check points in north sinai. 17 of its soldiers were killed while 100 fighters also died.

and egyptian special forces that killed nine members of the muslim brotherhood group among them was a prominent lawyer. and greece's prime minister, alexis tsipras said that as asked greeks to reject the deal. in iran's nuclear talks it would scale down it's program and not build nuclear weapons. in return sanctions would be listed. >> the detailed negotiations go on here still some sticking points and a great deal for them to get through because this is supposed to be the final agreement. they have a greet deal of detail to make sure that neither side

think the end of this when the deal is done that there has been some sort of misunderstanding. we understand that more foreign ministers will be coming here in the coming hours. the idea is to give this process momentum to try to get this moving towards a deal, which they want to achieve in the next week or so. perhaps more importantly though, the ministers coming here to vienna is the fact that the prominent figure is leaving vienna and going to tehran, the iaea he's on his way to tehran to meet with president rouhani. iaea is key because they would police any deal and there are controversial aspects of this. for example would inspectors be allowed to go anywhere in iran? would they be allowed to go to military sites. there are questions that the iaea have been asking for years about their past nuclear activities and there are some who say that iran doesn't come clean about what it has done in

the past how can you trust it in the future. >> let's go to syria where kurdish forces control much of the border with turkey. fighters belonging to the islamic state in iraq and the levant have said to be preparing amid rumors of offensive against them. turkey is also fearful of the prospect of further kurdish advances along the syrian border. >> the flags of turkey and isil just meters apart. it is under the control of islamic state in iraq and the levant. it's been a quiet weren't tear but that does not mean that there is peace with the group they call a terrorist organization. >> isil is on the syrian side. we protect our own borders. >> but isil is preparing for war. plant, explosives and digging

trenches. there are fears that there could be a planned offensive from syrian kurdish fighters. many believe its just a matter of time before the syrian town becomes a battleground and that battle will be decisive. it could change the front lines and the balance of powers in areas of syria. there are fears they would be able to control iraq kobane to further west. the kurds will not only capture isil controlled areas along the way. if they succeed they would control the entire syrian border with turkey and the main supply routes. turkey would see that as a threat. it's not just because it

supports of syrian rebel groups by considers the ypg a terrorist organization. the kurdish independent movement has been an issue for decades and there are reports it's military is considering across border operation to prevent kurds from gaining ground. reinforcements have been send sent to the border. >> for now the build up is now on the scale required for intervention, but the they say the option is on the table. >> at least 16 civilians have been killed and 25 wound in the rocket fired in the yemeni city of aden. they fired rockets in the streets in the monsour district.

officials say that hospitals in aden are overwhelmed and are working around the clock. well, the u.n. has raised its emergency response to the humanitarian situation in yemen to level three. that's the highest category. more than 1,400 civilians have been killed by fighting and saudi led airstrikes in march and 21 million people need aid many of them children. >> this young girl is inconsolable. [ sobbing ] >> shocked by what's happened to the homes in her neighborhood. houses that hours ago were still standing. >> why did they do this? she asks through her tears. in yemen devastation has become the norm. >> the situation is very critical especially for children who are the most vulnerable

groups. >> a collective trauma physical, and emotional that grows by the day. >> thinkthey don't have a protective environment to live in. they feel scared and insecure. >> hundreds die, some from wounds that are treatable if only they had access to better healthcare. the crisis here says this nurse gets worse because of the fuel shortage because children like this don't have access to transportation and can't get to the hospital when they need. [singing] >> in the shelter for the displaced boys and girls recite the qur'an. praying for the end of a war that has brought misery upon them. like the shortage of water in a country already running out of

the precious resource, and despite child malnutrition rates for a population already without enough food. a situation so dire that the u.n. warns that they could be on the verge of a famine. the pain in their eyes as easy to recognize as the bruises and burns on their bodies. then there are the others. their youthful appearance hides a suffering no one their age should endure. >> poor water quality pollution and climate change means that the future is bleak for the australian great barrier reef. but the report stopped short of formerly relabeling danger.

>> when you are diving on it most threats to australia's great barrier reef are not that obvious. although half of it has disappeared over the last 30 years, choose your spot carefully and there are still bright corals and plenty of fish. you don't notice the change due to climate change and the cold port built along the reef are from here far out of sight. but one threat once pointed out is all too obvious. the spikey thorn starfish. there is a plague of them they feed on coral and they're toxic to fish. scott is a team a part of team of people working to fight back. >> what they do to coral is quite amazing. the coral faces in this fits

enough threats as it is. >> the one starfish can produce 60 million eggs a year. far more are surviving than should. there have been outbreaks of thorn starfish in the past, but the latest is the worst and it's human actives on land that are largely to blame. >> growing sugar cane is big business along the east coast. it's farmers use fertilizers. but when the excess washing off the lands and into the sea it fertilizers the plank ton. >> we're applying chemical at 40% of the area. >> but once you put it everywhere. >> oh, yes yes. >> run off from our property it

goes into the saltwater. what we do on this land does effect the reef. >> but bugeja is a relatively young farmer around here. getting his neighbors to change their practices, too is not evening. when president barack obama came to speak to students he warned about the great barrier reef. >> still to come we'll have all the sports news. it's been the hottest day on record at wimbledon. we'll show you who has been in sizzling form. >> i'm jessica in london where a new show of photographs of the life of the beautiful audrey hepburn has opened.

>> these people have decided that today they will be arrested. >> i know that i'm being surveilled. >> people are not getting the care that they need. >> this is a crime against humanity. >> hands up... >> don't shoot. >> hands up... >> don't shoot. >> what do we want? >> justice. >> when do we want it? >> now.

>> explosions going on... we're not quite sure - >> is that an i.e.d.? >> "faultlines". al jazeera america's award-winning investigative series. monday, 10:00 eastern. on al jazeera america. >> it's now time to get all the sports news. here is jo and everyone is complaining about the heat. but the players in wimbledon must have felt it. >> absolutely. i expect they did we'll start where the blares have been battling it out in the 138-year-old championships. as the temperatures exceeded 35 degrees it was a case of trying to get the job quickly and comfortbly as possible in day three. >> where the forecasters were predicting one of the hottest days in more than 125-year

history of the championships in london it was not just the top players in danger. everyone had to take precautions against the heat. keeping cool was djokovic and betting nieminen, and barely breaking sweat. >> it was not as bad as i felt it might be something talking about it and predicting really difficult conditions. >> the women's french open champion serena williams is the world number one always in control of her contest. she will next meet of watson left in the draw who upset the vastly more experienced hantuchova in straight sets.

>> certificate serena is a great player. she's the one to watch in every tournament she plays. i think she's the one to pleat in tournaments like this. >> serena's sister venus is also into round three and going into straight sense gets putintseva. and maria sharapova. >> understanding that it's going to be warm and not going for too much because you want to make the points quicker than normal because of the heat and being smarter out there is the most important. >> and it is it was, indeed confirmed as the hottest day

wimbledon ended and the number 158 was too hot for the serbian player. >> meanwhile men's nishikori polled pulled out because of injury and that prevented him from taking on giraldo. >> very disappointed, especially in a grand slam, and i thought i was playing well, now i'm fortunate to lose this chance but i try to keep it up, and i hope i can do well in the u.s. series. >> and england will be hoping to make the final of the fifa world cup. for the first time in their history in just over an hour. they played defending champions

japan in edmonton, know that thatknowing that their opponents have gone unbeaten so far. but they can draw some confidence that they have never lost to japan in three previous encounterers. >> there is no situation, they are a great team, and we believe that our philosophy is just as good and we can come back out. and hopefully we'll stick to our game plan and i feel we can overcome them. >> the win already play usa .

argentina will host chile on saturday. >> hopefully we'll win it. we're very happy. rearrived very well and we'll play against a very good team like chile, which has been showing since the first game that it's one of the best. they're playing at home. it will be a difficult match. >> more than 20 foreign players are chasing their dreams in somalia's football league at a great risk of themselves and against the advice of their loved ones. somalia is an unlikely football destination, but it's capital city of mogadishu is now attracting footballers from the continent. >> they have come to follow their dreams of playing in a professional league.

coming, and more are expected soon, which is why the somali football association has put the limit of on the number of foreign players a team is allowed to sign. >> each team can only have four foreign players. it is to protect the local players. we can't have a league of foreign players. the foreign players have added to the excitement of the game. >> these fans have been waiting for this game all season. which ever team wins will have the brags rights for the next year. for now the teammates are celebrating the derby win and they say they can't wait until the start of the next season. al jazeera. mogadishu somalia. >> that's all the sport for now. thank you. >> now classic films like "breakfast at tiffany's" and "my
