been announced in egypt, following two attacks on coptic christian churches. more than a0 people were killed and many others wounded as worshippers gathered for palm sunday in tanta, which is north of cairo, and in alexandria. the so—called islamic state has claimed responsibility. greg dawson reports. this is the moment a suicide bomber approaches the cathedral in alexandria. a security guard turns away at the gate and directs him to away at the gate and directs him to a metal detector. seconds later, he deto nates a metal detector. seconds later, he detonates his explosive device. a day for christian celebration, transformed into a scene of horror. the head of egypt's coptic church, pope tawadros, had been inside, but was unharmed. this was a co—ordinated attack. the first target was the church of st george, in the city of tanta, also filled with worshippers. translation: the situation is painful. it's not fair.

the authorities have received warnings, before, that the church has been targeted. why weren't measures being taken to protect people? hours later, this response from egypt's president: translation: several steps are to be taken, the first of which will be the declaration of a state of emergency, for three months, after the necessary legal procedures are complete. we are announcing the state of emergency only to protect our country and secure it. the measure means the army will be deployed to help police guard important buildings, and security forces will be able to make arrests without warrants. it's a significant announcement — egypt had been ruled for almost two decades under a state of emergency. its unpopularity was a contributing factor in 2011's revolution. but it comes after the islamic state group warned it was going to intensify its targeting of christians in egypt. on sunday evening, the first

funerals were held for victims. egypt's copts have endured decades of discrimination. but after another day of grieving, a community known for its resilience is demanding greater protection in its own country. greg dawson, bbc news. president trump has told his advisers to prepare a full range of options to deal with the nuclear threat coming from north korea. a us navy strike group is already sailing towards the korean peninsula. president trump's national security adviser said the deployment was prudent and criticised north korea as a rogue, nuclear—armed nation. david campa nale reports. the carl vinson strike group, composed of an aircraft carrier, two guided missile destroyers and a guided missile cruiser, had been due to visit australia. instead, it's under full steam towards the western pacific ocean, where it recently conducted exercises with the south korean navy. as well as massive strike power, the carrier group has the capability to intercept ballistic missiles.

president trump made it clear to beijing last week that he's prepared to act alone against pyongyang if necessary. the decision to order missile strikes against syria, a reminder of his resolve. if you violate international norms, if you violate international agreements, if you fail to live up to international commitments, if you become a threat to others, at some point a response is likely to be taken. north korea's most recent rocket test, condemned by japan and south korea, came on the eve of china's president's visit to washington. and it follows the launch, one month ago, of ballistic missiles into the sea of japan. it is clear that their programme is moving forward at a marked pace. each test shows its rockets can go large distances, with established technology capable of striking of us military assets and allies in the region.

but the taepodong 2 system goes further, underlying an ability to put crude satellites into orbit. —— underlining. pyongyang says it has a sovereign right to do this. with satellite pictures suggesting yet another nuclear test may be close, the fear is that north korea will end up with a nuclear warhead capable of reaching mainland america. pyongyang says it has been provoked by military exercises between the us and south korea, which it sees as preparation for an invasion. as tensions rise, the arrival of china's nuclear envoy in south korea may hasten the resumption of six—party talks, and the role of diplomacy in solving the crisis. david campanale, bbc news. i discussed this with foreign policy expert nancy soderberg earlier. nancy's held many senior roles under president's bill clinton and barack obama, and has also served as an ambassador to the un.

she talked about donald trump's options in dealing with north korea. he absolutely has a range of options. in fact, he has asked his staff to do a blue skies planning, and give him some options, ranging from assassinating, you know, president kim, to negotiating a solution, to putting pressure on china. and i think that is a genuine "what are our options here?" the problem is that since ‘92, and the first president bush negotiated the entry into the non—proliferation treaty with the north koreans, the north koreans quickly figured out that the nuclear programme was the one currency in the international arena, and they've used it time and time again — they make a deal, and then cheat, they make a deal and then cheat. and then they throw nuclear hissy fits in between. it's the most difficult problem out there. and the actions that

president trump has are limited. you can't just bomb the nuclear sites. you can'tjust wipe out the ballistic missile sites. you can damage them, but you can't eliminate them. and the risk of attacking them is that you have worse fever, a worse of a, you know, momentum, for them. and so the trick is, and i think donald trump understands, is that you have to work through the chinese. and he just met with the chinese over the weekend, and we will see if they can be some kind of a diplomatic push, here. if not, i have no doubt that the administration will have some kind of — at least symbolic — military strike, which could play both ways. yeah, i mean, let's move on to syria because i want to get your thoughts on that as well. our focus there, because the us secretary of state, rex tillerson, has criticised russia for failing to prevent the chemical weapons attack on civilians. he said he would discuss russia's international obligations on chemical weapons, when he visits the country on tuesday.

here is some of what he said: i think the president was very clear, in his message to the american people, that this strike was related solely to the most recent, horrific use of chemical weapons against women, children, and, as the president said, even small babies. and so the strike was a message to bashar al—assad that your multiple violations of your agreements at the un, your agreements under the chemical weapons charter back in 2013, that those would not go without a response in the future. and we are asking russia to fulfil its commitment, and we are asking and calling on al—assad to cease the use of these weapons. other than that, there is no change to military posture. secretary of state, rex tillerson. nancy, back in 2013, the then—secretary of state, john kerry, reached an agreement with the russians to eliminate all of syria's chemical weapons. obviously that didn't work out.

when rex tillerson heads to moscow, this week, do you think you will have more luck achieving what president obama could not do, given what has happened in this last week? well, we don't know, but i think when president obama said the red line, and the russians came in and said "we'll stop that red line without military action," that deal clearly failed. the russians said they got rid of all of them, but clearly didn't. so i think the number one question is how do we get rid of all the nuclear — the chemical weapons stockpiled by the syrians. it's hard to do militarily. it is going to be a negotiated effort. and the russians are at the tip of that spear. that is going to be number one on rex tillerson‘s agenda, when he visits moscow, next week. secondly, what is our policy in syria 7 we do not have one. and we have not had one for the last six years. you know, hundreds of thousands of people dead. half the country — 10 million people — displaced, inside the country or out. and i think we need to look at another two—track policy. one is we have to defeat isis, there. and to do that, you are to work with the assad regime, the russians, and others.

and then, how do you solve the civil war? you've got an increasingly discredited assad, and actually, this chemical weapons makes it clear who this man is. and he has no legitimacy continuing to be president. and then you have the, sort of, opposition, that is somewhat difficult to predict. and we and the russians are on the opposite sides. you've got the saudis and the iranians if you want to put it in a regional context. and that is going to be a difficult problem to solve. so the us and the russians have to come up with a strategy that works. probably we will have to have some sort of use of force to back it up. as we have, force and diplomacy together equals peace. and that is a scenario that it could to take some time. so i would say isis, number one, and then a longer—term solution on what to do with this civil war in syria. and that is not going to be easy. we, for the first time, saw donald trump as commander—in—chief,

when he conducted those airstrikes, which had broad public support in the united states. now the question is can he be negotiator—in—chief? and we'll see. nancy soderberg, talking to me earlier. 20,000 people have gathered in central stockholm to remember the victims of friday's deadly lorry attack. swedish police say the uzbek suspect was facing deportation and had expressed sympathy with extremists groups. a british father of two has been named as one of the victims. danjohnson reports from stockholm. a square in stockholm close to friday's attack. time to stop, time to think. a chance to reflect on jumbled emotions, and on uncomfortable feelings, and to consider lives lost in a few terrible moments. chris bevington was one of those killed. a dad to two young boys who moved to sweden to build a life, a family, and a career

working for music company, spotify. his father said this: he was here in the crowded shopping street when a delivery truck was hijacked and used as a weapon. a belgian and two swedish citizens were also killed. police have revealed more about the 39—year—old from uzbekistan they believe was at the wheel. he has applied for permanent residence in sweden, he has been denied that. and he has been wanted by the police. this is where the truck ended up, smashed against a department store window. people have kept coming here to write messages of hope and defiance on the boards, and there have been more tributes to the victims too. just yards away, a display of the tolerance and kindness some fear could be at risk.

thousands shared their sadness, anger, and unease about the future. i want stockholm to be open, as it always has been for so many years. and now, all of a sudden, most of the people seem to be afraid, but still are very calm. we stand here in solidarity, notjust with those, like, in stockholm, but around the world, with everyone who needs tojust feel the love, and that we are together in this and we are not afraid. there was pride as well in the city's response. impromptu applause for the police and a message for those who threaten the way of life here. if we become scared then we play into their hands. i think this is a good picture of how sweden reacted. so far, that reaction‘s been solid. but tougher tests could still come. stay with us on bbc news.

still to come: 100 years on — remembering the soldiers who died at vimy, one of the bloodiest battles of the first world war. 25 years of hatred and rage, as theyjump up on the statue. this funeral became a massive demonstration of black power, the power to influence. today is about the promise of a bright future, a day when we hope a line can be drawn under the bloody past. i think that picasso's

works were beautiful, they were intelligent, and it's a sad loss to everybody who loves art. this is bbc news, i'm tom donkin. the latest headlines: egypt's president has declared a three—month state of emergency, following two bomb attacks on coptic churches, in which more than a0 people died. for generations, india has battled to put an end to sex—selective abortions. although it is illegalfor doctors to reveal the gender of babies during pregnancy, it is estimated that 600,000 baby girls are aborted every year. the issue is in the spotlight once again, after a grim discovery in the western state of maharashtra.

yogita limaye has this report from sangli. a horrifying discovery. the remains of tiny foetuses were found buried here under the soft mud. 19 of them, wrapped up in plastic bags, and cast away. it all came to light when 25—year—old swati jamdade died during a botched abortion. her family says her husband forced her to do it because she was pregnant with a girl. they complained to the police, and that uncovered a female foeticide racket. translation: my daughter will not come back, but at least these things will stop happening if some action is taken. as parents of a girl in india, you go through so much to bring up your daughter and get her married. but what's the use, if this is the end? police have so far arrested more

than a dozen people, including the woman's husband, and three doctors. translation: during our interrogation, we discovered that there are four middle—men engaged in the racket, and at least one of these doctors involved was terminating 2—3 pregnancies every week, based on the sex of the baby. this is the hospital where some of the abortions allegedly took place. finding out the gender of an unborn child is illegal here in india, and there is tough punishment for offenders, which includes time in prison. yet centres that conduct sex—determination tests continue to survive and thrive in many parts of the country. and that is because there is great demand for them, despite government campaigns to save the girl child. translation: the mindset in india is that a girl is a liability. if a female child is born, then the family knows that it will have to collect money to give

as dowry during her wedding. so parents think that, instead of raising a daughter, nurturing her, educating her, and then paying a large amount to get her married, they're better off aborting her. dowry is also illegal in india. but laws have very little effect on the ground. for many daughters of india, there are battles at every stage, and some don't even get a chance to fight. yogita limaye, bbc news, sangli. scientists claim two thirds of australia's great barrier reef has now been devastated by severe coral bleaching. they say aerial surveys of the world's largest living structure have shown damage in the central section of the reef, which stretches more than 2,000 km down queensland's coast. for more on this issue, i have been speaking to our correspondent phil mercer. well, for the first time, the great barrier reef has suffered mass bleaching in consecutive years,

and after aerial surveys, scientists are telling us here in australia that the middle section of the reef has been devastated by coral bleaching. last year, it was the northern part of the great barrier reef. so, if you put all of this together, it means that a stretch of 1,500 km of the world's largest living structure are now affected by coral bleaching. bleaching, by the way, is a loss of algae. it is caused by rising sea temperatures, and researchers here in australia believe that the government and the broader international community — well, time for them is running out to save the great barrier reef, unless more action is taken to try to combat climate change. and what kind of action are conservationists and the experts suggesting that the government do? well, the barrier reef faces micro and macro threats. when you think of the local threats

that the great barrier reef faces, overfishing, poor water quality, the industrialisation of that part of the australian coastline, those are things that the authorities are trying to address. most particularly water quality, trying to reduce pesticides and other contaminants running off from farmland, for example, into the great barrier reef. conservationists believe that the picture is far broader, and that the only way to save the great barrier reef into the future is to address the global problem of climate change. the australian and queensland governments say they are taking this very seriously, but today's report will highlight, from the conservationists‘ point of view, that time is perhaps running out. phil, you are there in sydney, so you know very well that the barrier reef is the jewel in the australian tourism crown. do you think that this new warning

will push the issue up the political agenda? it will do, and when you look at the significance of the great barrier reef, not only to australia's economy, it generates billions of dollars each year, it contributes about 60—odd thousand jobs to the economy, as well, but on top of that, it is arguably australia's greatest natural treasure, stretching for 2,300 km down australia's north—eastern coast. and conservationists hope that these sorts of warnings will now be heeded, and urgent action will be taken. the prince of wales, france's president hollande, and the canadian prime minister, justin trudeau, all gathered in northern france on sunday to mark one of the bloodiest battles of the first world war. more than 3,500 canadian troops died at the battle of vimy ridge. duncan kennedy reports. it was the battle that defined a nation, in a conflict whose horrors defied belief. today's commemoration at vimy ridge was a chance for canada to remember those who fell here,

and those who rose to the challenge of victory. the burden they bore, and the country they made. because this, too, is why we're here. why we remember. more than 3,500 canadians died in the four days it took to secure the ridge, an event later described as the moment canada came of age. today, beneath a world war i fly—past, prince william and prince harry laids boots and poppies, as symbols of loss and remembrance. this was a battlefield of corpses. the canadians at vimy embodied the true north, strong and free. in nearby arras, scottish

losses in the wider fight were also remembered today. greater love has no—one than this, that he lay down his life for his friends. the daily rate of casualties was greater than at the somme. among those to die was 26—year—old sergeant david wood, from edinburgh. we wouldn't be here without them, would we? we wouldn't be, you know, be free to do what we want, when we want. so they fought for us, and died for us, so we have to remember them, and thank them. there are no more combat veterans alive from the first world war. vimy ridge and arras are among the final great acts of commemoration, to honour their sacrifice, mourn their loss, and remember their lives. duncan kennedy, bbc news, at vimy ridge.

some golf news for you now, but notjust any update: sergio garcia has won the masters, in augusta, his first ever major title. but he did have to do it the hard way. going into the last round, he shared the lead with england'sjustin rose. nothing could separate them over 18 holes, and they went to a sudden—death play—off, where garcia was finally able to sink the winning putt. his victory, and that famous green jacket, comes on what would have been the 60th birthday of his fellow countryman, and idol, seve ballesteros. fans, family and friends have paid their final respects to rock'n‘roll legend chuck berry, who died last month. they gathered in chuck berry's hometown of st louis to pay tribute at the blueberry hill, where he performed more than 200 consecutive monthly concerts. a memorial service was held, where the 90—year—old's body lay in an open coffin, with his signature red gibson guitar bolted to the lid. among those attending was kiss frontman gene simmons.

the greatness is unequalled by anybody, in any form of music. and maybe chuck said it best. "roll over, beethoven. tell tchaikovsky the news. buckle your knees, bow your head. the great chuck berry is passing by." applause a reminder of our top story: president sisi of egypt has declared a three—month state of emergency, following two bomb attacks on coptic churches, that killed more than a0 people. and you can get in touch with me and the team on twitter. i'm @tomdonkinbbc. this is bbc news. good morning. sunday was a glorious day for many of us.

was it spring or summer? and really, it was hard to tell, because we had wall—to—wall sunshine throughout the day, and in parts of eastern and south—eastern england, highs of 25 degrees, 77 fahrenheit. you can see the clear blue skies from sunday's satellite picture, a little more cloud up into the north—west, and the cloud thick enough to produce some rain, which died off, and will continue to do so as this weather front sinks south. but this weather front is important, because as it pushes further south it produces north—westerly winds, a colder source of air, and that will bring a noticeable change to the story. we're losing the warm russets of sunday, as that north—westerly flow drags the cooler air across the country through the course of the day. so it's going to turn noticeably coolerfor all of us. as we start off the day, then, temperatures will sit at around seven to nine degrees, so not too bad, that frontal system bringing quite a lot of cloud. but up into the north—west, some of the showers will be wintry to the tops of the hills

and mountains, believe it or not. as we go through the day, we still run the risk of a few showers across scotland, one or two cropping up in the north—east of england. but i suspect by the middle of the afternoon it should be a better afternoon in south—west england and wales, where we had a bit of cloud yesterday, but temperatures at around ten to 13 degrees. we could see temperatures down a good 8—10 degrees in comparison to sunday's weather in the south—east, with a risk of a few showers in parts of lincolnshire and east yorkshire. heading up into scotland, yes, there will be the risk of a few showers here, but also some lengthy spells of sunshine. by the end of the afternoon, though, cloud and more organised rain starts to gather into the western isles, and this will be a weather front toppling over that high pressure, and start to push into the far north of scotland. high pressure really just exerting its influence still. across england and wales, here things will stay relatively quiet. chilly start to tuesday morning, a touch of frost in more sheltered prone spots, but clearer skies will lead to good

spells of sunshine. breezy up into the far north and there will be some showery outbreaks of rain continuing here as well. as we move into wednesday, we see more of a stronger north—westerly wind starting to pick up, gales not out of the question. but again, the best of the drier weather will always be further south, but there is going to be a fair amount of cloud around, i suspect, on wednesday, and on exposed coasts it will feel that little bit colder. little change as we go into thursday. what's in store for the easter weekend? the dry theme is set to continue. sunshine, and a few isolated showers, but that cool wind set to stay with us. the latest headlines from bbc news. i'm tom donkin. president sisi has declared a three—month state of emergency throughout egypt after bomb attacks killed more than a0 people at two coptic christian churches. the army will be deployed to help police protect vital installations and security forces will be able to make arrests without warrants. donald trump has asked his advisers to be prepared to give a full range of options to deal with the nuclear threat coming from north korea. a us navy strike group
