>> voting in burundi in a presidential poll, the u.n. and opposition condemned. hello. you are with al-jazeera live from doha. also to come on the program. >> make no mistake, the process of fully normalizing relations between the united states and cuba will go on. >> after more than 50 years the cuban flag flies again in washington. differences remain on both sides. turkey says isil was behind a

suicide bombing which killed 30 people on the border with syria. changing the way doctors are trained. we check out the latest in 3d printing. one person has died in burundi. the poll is boycotted by several leading opposition parties and the u.n., the eu and the african union said they won't recognize the result. there have been months of violence since thepresident said he would stand for a third term. >> i have covered a lot of elections in africa, i have to say this one in burundi is very

interesting. i have never been at an election where there is so much pressure for one man not to run for a third term. but he insists he's running for a third term despite violating the constitution. he says he has supporters who want him to keep ruling as long as possible. the election is going ahead and the people who are waiting at the polling stations, the people trickling in, they are hoping for one thing for their country. >> i have voted because we hope we will be united as one people are no differences. we want peace in our country. >> it was a night with gunfire and explosions. some people were killed. but voting is still going ahead anyway. the process is simple. you cast your vote, you come here and give them your i.d. card and use this ink to show you have voted.

there is a lot of tension. some people when they get the ink put on their fingerings, as soon as they leave the polling station they rub it off as quickly as possible, there is a concern they may be targeted for those people who think they shouldn't have voted. there is a lot of fear here. whether you want to vote or not people are concerned about the repercussions. either if you voted those that don't want the elections to go ahead, will an taking nice you. if you haven't voted people will ask why don't you have ink on your finger. a lot of tension in the country at the moment. people are waiting to see the outcome of the vote, more importantly what's going to happen. some people won't except him getting another term in office. we have been speaking to angela the outcome will likely

lead to more violence. >> the election itself is very important to the president. this is he was where he wants the country to go. i think he's hoping if there is an election, it's credit within the international community decreed among society and boycotted by the opposition, at least he can say he participated and contested for his seat as president in an election. that's very important. i don't really anticipate that the crisis facing burundi will end as a result of the election. that's wishful thinking on the part of the party. there will be more tensions within the country within the region the international

community will have to respond. it's in the interest ofny country or organization to intervene militarily for that matter. there will be a stalemate for some time to come, i think. i. the u.s. and cuba have restored relations after decades of hostilities. the u.s. cut off ties in 1961. that was two years after the communist revolution led by fidel castro. last december, the two countries agreed to reestablish relations after long talks that were encouraged by pope francis. an embargo is still in force. and travel restrictions imposed by both countries will remain in place. >> after talks with the cuba foreign minister, he will visit

cuba. >> translator: the united states welcomes this new beginning and its relationship with the people and government of cuba. we are determined to live as good neighbors on the basis of mutual respect and we want our citizens in the united states and cuba to look forward to the future with hope. many u.s. politicians are opposing the this. any attempt to scrap the economic blockade could face tough resistance. >> you will continue to see push back from congress. so if anyone thinks that the sanctions are going away, that the so-called embargo is going to go away, they have not been paying attention. >> there is some scepticism in that varyhavana. castro said i don't trust the

united states. doesn't mean i reject a peaceful resolution. >> reporter: it may look exactly the same, but this is no longer a u.s. intersection under the care and protection of the swiss embassy. that plaque is gone and the building you see behind me constructed in 1953 is now once again the u.s. embassy it was always meant to be. the american flag is not flying here. at least not yet. that will have to wait until u.s. secretary of state john kerry comes to oversee an official ceremony. but there are changes from the tiny american flags that the embassy staff were carrying to the number of tourists and americans carrying their passports and flags to mark this day. >> it's a historic event. hoping this brings about the changes. >> reporter: cuban whose go inside for a visa say the requisites have not changed. but according to this woman the staff was more friendly than

before when they denied her a visa. the reestablishment of diplomatic relations has a bigger impact here than in the united states. now u.s. staff will be able to travel around this communist island freely. of course, both countries have a long way to go to really normalize ties. but it has been an exciting day here. many are probably remembering former president fidel castro's prophetic words. in 1973 he was asked when he thought the united states and cuba would restore diplomatic ties. he responses when the world has a latin american pope and the united states a black president. he probably didn't believe it himself, but that day has come. turkish police have fired tear dbas to break up an antigovernment rally. they say turkey isn't doing enough to stop attacks by isil.

the demonstration follows a suspected isil suicide bomber killing 30 people in a town close to the border with syria. another 100 people were injured. >> the explosion happened in the garden of the cultureal center. most of the victims were volunteers, due to travel to the kurdish town close to the border in syria to carry out. it's not yet known what the cause is. turkey says it was a terrorist attack by a suicide bomber. there was also a blast. they prompted tens of thousands of people to escape to turkey. by january a combination of air strikes and the fighters defeated isil. much of the town lies in ruins.

many blame the turkish government for not doing enough. >> many turkish kurds accuse their own government of taking a proactive stance in favor of isis. particularly at the time of the siege, the turkish government seemed to have the attitude that the enemy of my enemy was my friend. and, therefore they sat on their hands during the entire siege. >> reporter: families are mourning after escaping the war in syria many hoped they would be safe here. this explosion has proven them wrong. >> a group linked to isil claimed responsibility for an attack on a mosque in yemen. it happened in an area close to a houthi rebel leaders home. six were killed in a shooting at a checkpoint and five others are dead after a car bomb exploded

at a police station. in the southern part of the country, an international aid group says a hundred people have been killed by houthi shell can. doctors without borders say many civilians are among the dead including women and children. the rebels and allies attacked the neighborhood on lot more to come on the program including former president's top aide is the latest in china's crackdown on corruption. we'll be live in beijing.

>> government committees. >> they're spending money, they're not saving it. >> costing millions and getting nothing. >> it's a bogus sham. >> america tonight investigates. money for nothing. >> they've gotten away with it for years.

>> hello again. you are with al-jazeera. these are our top stories. one person has been killed in burundi as people vote in a controversial presidential election. the incumbent is running for a third term. the u.n. and eu all say they won't recognize the results. the restored diplomatic ties with the u.s. will work only if the economic blockade of havana is lifted. on monday the two sides reopened talks after decades of hostilities. antigovernment protests in turkey following a suspected isil bombing. the government isn't doing enough to stop attacks by the group. 30 people were killed in the attacks. the iranian foreign minister has been defending last week's nuclear deal with world powers

back home. he told parliament iran will closely monitor the implementation of the accord. he's our diplomatic editor. >> this was the moment the iran deal was ratified by the u.s. security council. the vote will make it binding international law. it starts the clock on the program for the implementation of the deal known as the joint comprehensive plan of action. sanctions imposed in six previous u.n. resolutions will be lifted once the nuclear agency, the iaea confirms that iran scaled back its nuclear program. >> 90 days from today when we have had a chance to review the deal's provisions, the commitment in the jpcoa should take effect. it will begin when iran completes the stepsness try bring its nuclear program in line with the deal. >> iran's ambassador to the u.n.

made it clear the deal could have positive repercussions beyond his country's nuclear program. >> we hope that it helps turn the page in our region enabling countries to close the ranks and fight against violent extremism and move towards more cooperation to act against the grave threats that our region and the world face. >> reporter: israel's ambassador to the u.n. was not invited to speak in the security council. he made sure he briefed reporters the moment the meeting ended. >> today you have awarded a great prize to the most dangerous country in the world. >> reporter: there's also been angry reaction to the vote on capitol hill. the u.s. congress has 60 days to review the deal with iran and u.s. diplomats hoped that the u.n. security council vote would take place after the review period. but the tough negotiations in

vienna, the timing of the vote was con of the concessions that needed to be made. israel has been warning the u.s. defense secretary that it says the deal will mean more money for hezbollah. he's trying to reassure regional allies. after talks he said the u.s. will continue to closely monitor iran. but for his part, he said the deal will strengthen groups hostile to israel. he's due to prime minister benjamin netanyahu on wednesday. he will then go on to jordan and saudi arabia. north korea says it has no interest in a similar agreement with the u.s. they are already a nuclear weapons state and can't be compare with iran. it's subjected to international

sanctions. north korea staged three successful nuclear tests in the past nine years. a former chinese president's top aide has been arrest in a corruption investigation. wah has been expelled from the communist party accused of accepting brides, keeping mistresses and stealing party secrets. his arrest is part of an anticorruption campaign. let's go to scott in beijing. so this man was very, very, comes from the top echelon of the chinese communist party. >> absolutely. he was at the center of power. what's interesting to see is that we have seen a pattern like this three times before with this anticorruption campaign by the current president.

this is the fourth top former official who has gone through this pattern. first, it starts by side lining the political career, putting them on smaller roles and then culminates like we have seen today. and that is that these charges have been brought up, kicked out of the party. they have been detained. this is the latist in the round. what's interesting, because this is such a campaign, a personal campaign, when he came into power back in 2012, he said this is one of the most important things his presidency, anticorruption, that you can bet over the coming months when this trial goes through the process this will be big news and it will be publicized. the government wants it to be. >> he has a string of accusation accusations. his son was associated with ratherrather lurid scandals as well. >> absolutely.

2012 was the beginning of the end. that was a high speed crash of a ferrari here in central beijing. in that crash his son was killed. there were two women with him in the vehicle. both hurt in the accident. one later died. so there is controversy around that. there was a coverup that didn't work after that crash. that's where the beginning of the end came for him. it reads like a soap opera including trading power for sex adulterous affairs corruption, shearing core secrets of the communist party. those are high charges. it will be interesting to see how trial against him goes during the next couple of months. toshiba's high executive are

stepping down. the $1.2 billion accounting scandal is another blow to corporate japan's image financial fraud was uncovered at camera and medical equipment maker olympus. this is a live shot. toshiba is trying to get an explanation. this is a scandal that started when market regulators found problems while investigating the company's balance sheet earlier this year. that's a live event as you can see. we'll keep our eye on events here at al-jazeera. demonstrators have been scuffling with police in nepal. they stormed the stadium. they are angry about a draft constitution. they say many minorities are being excluded.

>> the draft constitution in flames. people from the town angry at not being allowed to participate and present grievances on the new constitution. earlier scuffles with leaders including the former prime minister didn't include them in their survey. >> translator: they created the procedure. they made police detect the locals. >> reporter: the government declared a public holiday. but there is tension across the entire southern belt of nepal as locals protest and demand that past agreements are respected. also suggestions were collected under heavy police presence. people are concerned that this constitution is going to make them worse off. >> translator: federal states

have to be demarkated. this is pure arrogance. >> reporter: people have always felt neglected by the center. they are concerned about citizenship. more than 4 million people in nepal don't have it. the new draft constitution says that both parents have to be nepal for children to be nepali. >> even after waiting for the 15 years, the kids would be naturalized citizens. >> traditionally, they have always married across the border in india. now many of their children won't be recognized as nepali. they are trying to push a regressive constitution while the nation is reeling from april's earthquake. unless the grievances in this part are addressed it will

flare-up again. it's a year since the european union and united states imposed economic sanctions on russia. moscow is accused of backing separatists. >> reporter: the shelfs are full but polish apples have been replaced. there are no cheeses or meat or dairy products from u.s., canada or australia. it's costing her more to feed her family than it used to. >> the prices have gone up. i think many people like me find any deals helpful. all categories of food have gone up. >> reporter: she has fewer

rubles to spend than she did before the war start in ukraine. the eu, u.s. and other nations wanted to punish moscow for its part in the crisis, imposing financial and trade sanctions. in turn, russia imposed its own measures including a blockade on many agricultural products. couple with a drop in worldwide oil prices, the ruble has slipped against the dollar, making everything more expensive and the market more volatile. but what has remained stedfast is support for the russian president. his gamble appears to have paid off. if the west was hoping that the sanctions would hurt vladimir putin personally, they haven't worked. his popularity rating is sky high bolstered by the crisis in the ukraine. but with a growing sense of isolation, old fears have come to the surface. and different relationships are

being worked on. >> russia is a european-minded country. part of the western community in general terms. now they feel alienated, they are subject to a new crusade. and that definitely backs up the policy, a pivot to asia. >> no one knows how long the effects of the sanctions will last or what the ultimate price will be. >> european union ministers have failed to agree on how to relocate 40,000 migrants from italy and greece. they were supposed to reach a deal by the end of this month. but that's being put off until december. most of the migrants are from syria. another 600 migrants were brought ashore on monday by the italian navy.

floods in southern brazil forced the evacuation of more than 2,000 people. areas near the city were badly hit. some residents needed boats to escape the rising waters. more rain is forecast for tuesday. they have printed everything from guns to shoes. now 3d printers are making replicas of body parts. medical staff at an australian university are pioneering the technique which can change the way doctors are trained. >> reporter: caked in this powder is the latest innovation in 3d printing. replica body parts. designs based on ct scans of people who are colored within the computer to create a file to send to a 3d printer. it build as block of powder in thousands of incremental sweeps. with each sweep the printer head

injects solidifying colors into a portion of the powder. as the block is lowered a detail limb forms within. >> we had a head, printed a face and head and the muscles around the face and neck and rising out of the powder, very erie, but very amazing. >> the parts aren't suitable for implants in people. but accurate replicas of parts can be useful for training doctors. traditionally students learn from books models or occasionally from parts dissected from dead people's bodies. >> two hour as week. it's great having the cadavers there to have that 3d aspect or having that practical aspect to what you are learning in your textbooks. i suppose you could argue it is less than what we would want.

>> cadavers are rare and expensive and in some cultures they are taboo. >> there are some cultures and religions which frown upon the dissection or interference with a dead body. i would like to think that the parts of the world where there are teaching with cadavers, this could fill a unique niche. >> the accuracy is what makes them special. molded models can't get close. in timeso far there hasn't been a complete body printed. there isn't a machine big enough to do it. this is a mix of body parts based on scans of different people. although this isn't the start of being able to print something that could be given life, for science teaching it is a big footstep forward.

>> if you want to find out more about 3d printing body parts go to www.aljazeera.com. you can follow closely our lead story today, that is the controversial presidential elections taking place in burundi. www.aljazeera.com. >> this is "techknow". a show about innovations that can change lives. >> the science of fighting a wildfire. >> we're going to explore the intersection of hardware and humanity, but we're doing it in a unique way. this is a show about science... >> oh! >> oh my god! >> by scientists. >> tonight, techknow investigates shrimp safety. >> seafood by nature is a high risk commodity. >> americans love their shrimp but most of it comes from countries that use extensive antibiotics th
