Supporters of Muhammadu Buhari are celebrating his victory in the Nigerian presidential election. Mr. Buhari issued a statement thanking Nigerians for voting for him, but he urged his supporters not to harm opponents or destroy their property. Will Ross reports from Abuja.

“Finally, the long wait is over. The opposition's General Muhammadu Buhari has won this pivotal contest. His party says President Goodluck Jonathan has called to concede defeat. Never before has a sitting President lost an election, and it feels as though Nigeria has turned a corner. The outcome may be disputed by some, and there is still a fear of violence. But many Nigerians feel, for the first time, they have the power to vote out a government that's not performing well.”

The Turkish security forces have stormed a courthouse in Istanbul where a prosecutor was being held hostage by members of an outlawed Marxist group. The prosecutor was in charge of the inquiry into the death last year of a teenager, Berkin Elvan, who was hit by a teargas cannister during anti-government protests. Our correspondent, Salin Garrett, was outside the courthouse.

“The prosecutor who was held hostage for over 7 hours was taken seriously-wounded to hospital. The President made an announcement saying that he was shot three times in the head and he got two shots in the body. The Police Chief made an announcement after the operation ended, and he announced that the two militants who held the prosecutor hostage have been killed. He said the operation started once they heard gunshot, a gunshot being fired in the prosecutor's room, although the negotiations were being held.”

International talks in Switzerland on Iran's nuclear program are to continue beyond a self-imposed midnight deadline. The U.S. State Department says several difficult issues remained, but enough progress have been made to merit going-on into Wednesday. Barbara Plett Usher reports from Lausanne.

“The foreign ministers have huddled in meetings all day. A senior State Department official said they were making progress. They are trying to reach a framework agreement, setting out the political parameters of a deal, which would be used as a guideline for technical experts to work out the practical details. Despite 18 months of negotiations, disputes have persisted on key issues, such as limits to Iran's nuclear research program, the timing and scope at which sanctions would be lifted, and what would happen to Iran's stockpiles of enriched uranium.”

The Vatican has defended the appointment this month of a bishop in Chile, who's been accused of covering up sex abuse by a priest.

Iraqi government forces say they've made significant gains in their battle to drive Islamic State fighters out of the city Tikrit. The Prime Minister, Haider al-abadi, was quoted as saying that it had been liberated after the army and its militia allies captured a complex of government buildings. But reports from the city itself suggest that the fighting is continuing. Mike Wooldridge looks at the Iraqi bid to recapture the city.

“The military challenge of recapturing Tikrit intensified as they moved towards it over the past month. And there were increasing reports that the IS militants have planted hundreds of booby trap explosives in and around the city. Then it's been complicated politics over Iranian-backed Shiite paramilitary groups supporting the Iraqi government forces. These groups suspended their operations when Iraqi Prime Minister requested the help of U.S. airstrikes last week. Such controversies may now have been overtaken on the ground, if the government's triumphal pronouncements today are taken a faith value.”

The European Union has made similar commitments to cut its carbon pollution, while China has given informal commitments.

伊拉克政府军称在将IS武装分子驱逐出提克里特的战斗中取得重大进展，总理阿巴迪称在部队和民兵联盟夺取一个政府大院后，该市就解放了。但来自该市的报道称战斗仍在继续，麦克·伍德里奇在伊拉克报道。
