as president thanks iran for a fair negotiations after the 2 countries exchange prisoners on what's being called a humanitarian gesture. and we shall carry this is al jazeera live from doha also coming up several saudi nationals in the u.s. are questioned over the deadly shooting at a naval base. an escalation of violence in iraq since thousands on through the streets to protest what they call the slaughter and baghdad. is on top of the world is once again the boxing heavyweight champion of the world after beating and.

as president donald trump has thanked iran for very fair in negotiations that led to a prisoner swap between the 2 countries were diplomatic breakthrough was brokered by switzerland and it comes as the u.s. maintains tight sanctions on iran over its nuclear program and the chapelle has more. 2 men caught up in tensions between the united states and iran able to reunite with their families after a prisoner swap american graduate student. and iranian scientists mustered sulaimani a stem cell expert who'd been treating stroke patients at the best hospital in the nation the mayo clinic in minnesota so the money was arrested last year while trying to take medical materials back to iran it was far cheaper to buy in the united states prosecutors said that was a violation of u.s. sanctions going to be. welcomed with tears he's back with his family and

patients after spending a year in jail and i do you know. i told them that i had patients that needed my help and they said who cares let them die michael duffy on the same tarmac incirlik she was welcomed by the point man of trump's maximum pressure campaign brian hook a graduate student at princeton university chinese born wang maintains he was conducting research in iran for a history degree when he was convicted of espionage and sentenced to 10 years in prison recently at least where it is by no means his wife who campaigned for his release for 3 years said he was criminalized for his american citizenship. saturday's prisoner swap a rare acts of cooperation between the u.s. and iran president trump even thanking iran for a very fair negotiation i think it was a great thing for her and i think we wait to go then we can do something that might have been a a break during during the what could be done dozens of iranians remain in u.s.

prisons while at least 4 americans remain behind bars in iran returning them a priority for both countries whose long list of grievances rarely see such moments of cooperation and or chapell al-jazeera. is executive vice president of the quincy institute that is a political thing tank he says the success of the swap may open the possibility of more prisoners on both sides and frayed. i think they're very hopeful that perhaps something will take place because for the 1st 2 years of the trumpet ministration even though there had been existing negotiations during the obama administration that simply could have been continued they were really knocked pursued with the type of vigor that was needed so i think this is a very significant breakthrough in the sense that it does indicate that the trumpet ministration is interested in such a swap and having succeeded this time perhaps they will be willing to go forward and negotiate a swap for the other prisoners and whether that thing can create a foundation for further diplomacy between the united states and iran of course

remains to be seen but it should be noted that even the 2015 nuclear agreement one of the key components that a key channels that was used in order to reach it which was through the omanis that channel actually came through as a result of the omanis intervening and helping 3 american prisoners get released out of iran and it was also a prisoner incidentally earth korean state media says the country has says conducted a very significant test of its satellite launch site hours earlier that denuclearization was off the table and any future talks with the u.s. or crazy bastards at the u.n. added washington's efforts for ongoing dialogue or solely for its own domestic agenda talks on the nuclearization have been largely deadlock since a summit between donald and kim jong un failed and february the saudis didn't behind a deadly attack at a u.s. naval base in florida is reported to have played videos of mass shootings at a dinner party earlier in the wait on friday saudi national mohammad saeed. shot

dead 3 of his fellow students at least 8 others were injured before he was killed by a deputy and that's innocent questioning 10 saudi nationals in connection with the shooting as defense secretary says it's too early to call it an act of terrorism. course we extend our condolences to all the families affected by it and touched by it and our military community. but no i can't say it's terrorism at this time i think we need to let the investigators do its work and tell us give us the facts and we'll move from there. i can and washington says investigation is focusing on whether the gunman acted alone very early days in the investigation being carried out or headed by the f.b.i. both in the u.s. and also f.b.i. agents sent to riyadh to cooperate with saudi intelligence authorities there but certainly the latest news that at least 10 saudi nationals have been detained on the base indication of the possibility of

a wider conspiracy and not just the act of an individual equally that individual the gunman who carried out the attack his reports about a twitter feed that he had indicated an alert allegiance to an alliance with the sama bin laden as well as intense criticism of u.s. policy in the middle east in particular relating to jerusalem another indication of some kind of outside involvement was an associated press report that one of the saudi nationals detained on the naval base filmed the entire attack while it was taking place inside a classroom complex on the base but still as we heard from the secretary of defense investigators nowhere near any firm conclusion they will continue to do their work in establishing what the real motive was behind this attack. and as president donald trump says saudi arabia was sending its condolences but didn't say a free op would be helping in the investigation but with the king of saudi arabia.

they are devastated the arabia we're finding out what they're like whether it's one person or a number of people and the king will be involved in taking care of family and loved ones feel very strongly very very devastated by what happened what there. are some is director of the center for middle east studies at university of denver it's home a college there in jordan authorities could soon be looking at the involvement of other saudis present at the base of the time of the attack while the reporting that we are receiving does suggest that this attack. involved more than one person i mean this idea that several of the saudis on this at this air base where she'll make the attack and some were watching from the car and then there's this report that the attacker had a twitter account where he was echoing statements that are similar to the world

view of osama bin laden does suggest that the investigation unit is heading in the direction of a wider sort of terrorist plot here and president comes response so far has been quite restrained in contrast to some of his posture reactions to violence by people from muslim majority countries is that because of his cozy relationship with the saudis. well i think that's largely what it has to mean that largely explains trump's response recall that he's spent a lot of political capital and energy trying to cover up the murder of jamal khashoggi he's praised the saudi crown prince there trying to put the controversial issues in u.s. saudi relations related to the murder of jamal khashoggi and the use of u.s. weapons in yemen to commit war crimes trying to try to put that all behind him and say that you know things are going very smoothly there's a lot of money to be made with between the 2 countries let's move forward this

event if it's proven again if it's proven to be a wider terrorist plot is going to make life very difficult both for donald trump and for mohamed bin so on yeah and that's an interesting point you make because how embarrassing is this shooting for the saudis who as you say have been trying to project an image perhaps of moderation off of the will this shooting now undermine those efforts do you think. well i think it does because it's going to raise questions you know is this particularly if it involves you know more than one person the obvious question is to what extent. are the behavior in the world view and the the the radicalized positions of these attackers to what extent do they represent you know public opinion among young people in saudi arabia that's a huge embarrassment for the saudi crown prince who is trying to project this you know image of of moderation and of progress but for donald trump it's also

embarrassment on another point where i mean i know the point that i'm speaking of is the question of the muslim travel ban saudi arabia is not on that ban will other countries are and this is going to raise questions about. the muslim travel ban about you know why saudi arabia is not on that list of countries and it's going to be i think very embarrassing for both countries not just a final question to you i mean this isn't the 1st time that saudi nationals have killed the u.s. citizens on u.s. soil just go back to 911 to think of that is it likely then to revive coals by us no make has long been demanding a complete overhaul of u.s. saudi relations well absolutely there's a lot of saudi sentiment in the united states both at a popular level and in congress all of the major candidates who are running for president in the democratic party have publicly stated they want to re-evaluate and reassess u.s.

saudi relations so this incident if it's proven to be a terrorist incident involving saudi citizens is going to raise the political temperature and raise the call and the demand for rethinking u.s. saudi relations so it's it's a big deal. to iraq where there's been a dramatic escalation of violence in the past 2 days on saturday an armed drone targeted the home of a prominent shia cleric and he was not home at the time as spokesman has warned of such an attack would lead to a cold war. at 3 40 am a drone was carrying a bomb which fell near the home of mr bush brother it was an unfortunate and unacceptable incident groups that want to incite conflict but our brothers of the southern movement are dealing with the situation and with lots of wisdom they initiated the call for calm. faultiness following developments and baghdad just as the government's response to the violence has been slow well the ministry of

interior has said it has begun an investigation into last night's attack i think tags but as of now it's still uncertain who is responsible president barham salih issued a statement just a few hours ago blaming the attack on criminal gangs and outlaws so it's still unclear at this point who exactly is responsible the protesters themselves have blamed militia as well as parties for this attack but this is something that hasn't been confirmed at the moment the parliament has also called for an extraordinary session tomorrow morning several military commanders to try to better understand this situation but for now the slow response of the government has been very slow and has raised concerns among protesters that as this violence really risks escalating even more the government should take a much stronger stand and push for a fast investigation to really bring those responsible to account. still ahead on

a columbus the boat was anchored on the sea shore in the smugglers were scouting for passengers my grandson and 2 others heard about this and they decided we were hopeful that they were going to succeed. out of 150 mostly gambian migrants 85 managed to swim to safety and were found by the mauritanian military near the northern city of what they were given food cloth and shelter by mauritanian authorities and various you and agencies including the international organization for migration. the room to receive treatment at the local hospital the bodies of dozens. buried outside on thursday i paid more than $700.00 to get to europe i took the ship with gambians and the single when the disaster happened we were on the edge of death thank god we are risky by the mauritanian authorities i am from the republic or senegal i was on my way to spin

a bill for an extradition deal with china and the protest movement might well have ended then if hong kong's chief executive kerry had heeded their demand to go absolutely had succeeded with the withdrawal of the bill to safeguard our freedom nothing would have happened. benson haute never saw him self as a front line activist but that's what he's become he's been arrested and forced to leave home. i told my dad we're going out to fight for the rights we deserve we had a big fight and after that he said move out move out if you don't want to stay at home anymore. bensimon is also there when protesters smash their way into the heart of hong kong's government the debating chamber of the legislative assembly many wearing the hard hats and face masks that have become symbols of this leaderless movement. as the long hot summer rolled on the air became more toxic.

it was now a color many in white chasing and beating those in black the color of the protest movement. tara i said again tara but terrorism aided by foreign hands is how beijing defined it after its liaison office in hong kong was attacked and defaced. mainland owned businesses were also targeted. as were transport links subway stations were vandalized and forced to shut tunnels were closed and thousands of flights canceled after protesters occupied the international airport arrivals lounge chinese leaders have repeatedly warned they would send in the people's liberation army to restore order yet that still hasn't happened they fear that if they work mobilize the people's liberation army garrison in hong kong than china will lose face because. chinese rule.

they have not won the hearts and minds. police figures reflect a society tearing itself apart at least 2 deaths more than $10000.00 tear gas canisters fired and almost $6000.00 arrests. more fatalities seem possible after students turned a university campus into a fortress the fiery standoff with police becoming a defining moment of the unrest in spite of the violence local elections went ahead with voters sending a clear message of support to those agitating for greater democracy a few days later there was another setback for china's leaders u.s. president donald trump signed into law a bill aimed at protecting human rights in hong kong and punishing those deemed responsible for suppressing them many of the protesters i've spoken to during the

past few months concede the deep down they know they're not going to win but they also stress that their movement represents the best about its last opportunity to achieve more democracy. adrian brown al-jazeera hong kong. and lebanon thousands of women in march to protest a sexual harassment when men are fighting to change a system they say has been unjust to them and is in a hotel reports from beirut the wider anti-government protest movement has given them a new platform. but they are speaking out in solidarity with those who recently gathered the courage to do so a flash mob was organized by lebanese women to support others who have been sexually abused harassed dozens have broken their silence of the past few weeks since the start of the so-called october revolution in a society where the victim and not the rapist is condemned this is a challenge to the norms of this revolution has given strength for many many many

women in the minority. the women speak up including the. choice of. the government taking into consideration. an anti-establishment movement against the ruling elite has given these women a new platform like other lebanese they are calling for an end to corruption unemployment better living conditions and an overhaul of the political system there are so many discriminatory laws against women and i'm going to just state the main source of the problem it's the fact that we have no civil code for personal status so basically there are really just courts that's right now we're at fairs lebanon is home to many religious sects whose leaders preside over personal domestic issues such as marriage and divorce women have. been vocal role in the protest movement against their leaders they have taken part in protests

a blocked roads led reconciliation and by crossing frontlines in order to preserve national unity for many of them this is their chance to bring down the sectarian political system that human rights groups so. make them victims. activists say one in every 4 lebanese women have been assaulted yet there are no laws that criminalize sexual abuse and harassment women also have little protection from violent partners custody of children more often than not is granted to fathers and the list goes on bringing about change will be. the greatest thing. so i will i would always encouraged. because. if you want to peaceful revolution we're going to have to give it its women who have been challenging the system for years are no longer alone in calling for a secular state the uprising may have divided society but these women believe there is already a new beginning for their beirut. a 3rd successive day of nationwide strikes and
