at regaining the support and give them a morale boost if you like. >> the hardliners musting questioning their role in iran now that this deal has gone through. do you see the hardliners' influence being affordable if or when these sanctions are lifted and when the country becomes more open? >> well, i believe, that the hardliners politically, they are in decline. they might sound more rhetoric. they might see more rhetoric coming out of hard liners but i think they are in decline. we have parliamentary elections in about seven months' time and i think they are quite worried about their chances of winning that election. >> as you say, the hardliners' influence are in decline and now that we are about to see the sanctions being lifted iran is going to be a very different conducts country to the ones that we are

used to before the sanctions. >> yes. but you mustn't -- you mustn't expect the ayatollah to change his words and his look overnight or for that matter the hardliners. it's only natural to expect them to carry on with the same rhetoric, but in reality, i think moderate reformists are -- have a better future. >> the nuclear deal with iran is seen as a major success for u.s. president barack obama and one of a string of reece event achievements which will help to secure his legacy. white house correspondent patty culhane takes a look at what's next. >> you can see it in the way he walks. suddenly for u.s. president barack obama, fired up seems like more than a campaign slogan.

mass shooting. ♪ how sweet the sound. ♪. >> i has been a defendant bit blunt when he thinks he needs to be? >> that's nonsense. you should know better. >> his on to do list isn't done. it's possible he will be able to get through criminal justice reforms and he is still working on finalizing the transpacific partnership, a free trade agreement that would impact 40% of the global economy. analysts say what the president and the staff have probably figured out by now that often presidential legacies are shaped by events outside of their control. >> when it comes to foreign policy, obviously everything is completely unpredictable. there is so much out of his control, what other world leaders do is out of his control. terrorist attacks are out of hi control. >> i faces challenges the fight guess isil the rebuilding of iraq, the civil war in syria, the stand-off in ukraine and he needs to get the iran deal past congress and figure out if he will do more than just threaten

israel with the possibility of supporting palestine at the united nations. this is a president who realizes the clock is ticking, hoping he can tick off a few more accomplishments in the time left. patty culhane, al jazeera, washington. >> security has been stepped up in diyala province. the governor has closed public parks and entertainment venues and declared three days of mourning. imran khan reports. >> reporter: the governor of diyala province called for three days of mourn after the most serious attack there this year. the explosives were detonated as people celebrated the eid religious fest vavl. a suicide bomber drove into the middle of the marketplace. you can see buildings have been damaged. ideal would anyone ever do this? this is terrible on the mourning of eid when everyone should be

celebrating. >> bodies were being pulled from the rubble angry crowds destroyed property and cars in protest. social media accounts linked to isil claimed responsibility saying sshia muslims were the target. isil said it was revenge for the iraqi government's campaign against the fighters and the death of sunni muslims. as three days in morning are declared, public places have been closed to try to prevent further attacks. imran khan baghdad. >> a shopping mall in kenya has re-opened two years after thebeing attacked by al shabaab fighters. four men with grenades and automatic weapons took over the westgate mall. >> we willlet's hear from one woman who was inside sher shop in the mall when it was attacked. >> my name is nadia, and i am from the frankrance lounge. we are ready to open back at the

westgate. on that day, he was here. i ran out in a very very bad state. it was the worst day ever. i had to come back into the mall after a few weeks to recover the stock. initially it was very hard for me to come back in. i came to terms with it. we are ready to open. we are ready to sell. are people going to come in? we feel comfortable but we invite people to overcome the fear. for people who are hesitant coming into the mall i feel like we should come together as a community and support because as a country, we are going through this as a country, we are not going through this as just westgate because it can happen anywhere at any time. it's not because it happened here it's going to happen again. it's because we are back here.

we have overcome it. we are ready to do what we are supposed to do. so we urge everyone to support us. the security is -- yes, we have moved from where we were. we are much better than what we were two years back, but i think we have a longer way to go. >> yolanda buckhar is from the institute of securities studies and she says there is room to improve coordination of security services in kenya. >> there has been various attempts to change the past leadership in the military and in the security. but beyond that, it's very difficult to say what has been done concretely to instill more discipline. i think another issue with regard to the response to westgate was the fact that you had two security institutions competing for the leading role on the scene. you had the gsc and you had the military. there needs to be a clear stanchion in the future. i think the government has been working towards that on clear

chain of command, when you have domestic terrorism in an urban setting, do you send the military or do you send a counterterrorism unit? this is one of the reasons why the westgate event was so problematic. i think the government has been trying to approach that much more systematically. >> administering the university of sudan are trying to figure out how to prevent students from dropping out of their studies to join isil. and as al jazeera's natasha gname reports, more than 20 students are believed to have joined the group. >> reporter: together for a better future is the motto of the university of medical sciences and technology until
