As voting continues in Brazil's elections, the incumbent president Dilma Rousseff has acknowledged that she expected to have taken part in a runoff vote against one of her two rival candidates, the center-right candidate Aecio Neves and the popular environmentalist Marina Silva. From Rio de Janeiro, here is Julia Caneiro.

The big question today is who would make it with her to a second round? If it's Marina Silva, the surprise of this race, she surged in opinion polls after the death of former candidate Eduardo Campos and seemed to have very big chances, and Aecio Neves was pushed back when she entered the race, but now has recovered positions and according to polls we saw last week, was threatening closing in on Marlina. It really seems like this will be decided vote by vote.

A fierce gun battle has been taken place around the besieged Syrian town of Kobani near the border with Turkey. Kurdish fighters backed by US-led airstrikes had tried to hold back Islamic State militants. Paul Adams reports.

The battle for Kobani has intensified once more. From our position across the border, we watched a furious gun battle seem to engulf the eastern edge of the city. In the distance, we could see tanks moving and the muzzle flash of a heavy machine gun. And a war came briefly to the Turkish side as well. We found angry defiant Kurds clustered around the house that'd just been hit by a rocket fired from across the border. Several people have been injured. The Turkish authorities quickly evacuated nearby villages, firing volleys of teargas in an effort to hurt people away from the border. Once again, violence on the Turkish side had distracted it from a much more desperate struggle going on across the border.

There have been fierce clashes in eastern Lebanon between Islamist militants and the Lebanese Shiah group Hezbollah. Reports say the Islamist gunmen believed to be from the Islamic State and the Nusra Front crossed from Syria and attacked Hezbollah positions. Several people have died. Tension has risen in Lebanon since the army attacked Islamist forces who seized a border town last month.

Exit polls from Bulgaria snap election have pointed to a comeback for the former bodyguard Boiko Borisov and his right-wing Gerb Party. But the Party was not expected to secure a majority of votes, making another coalition government likely. From Sofia, here is Nick Hope.

If the exit poll results are born out(证实) by the real count, Gerb, which stands for citizens for the European Development of Bulgaria, which led the country into February last year, looks set to head the next coalition government. But the task of the Gerb leader Boiko Borisov would be made more complicated by the plethoric parties expected to cross the 4% threshold and to enter the new parliament. The next government will be the fifth in under two years in Bulgaria. It would have to decide rapidly on the fate of the major commercial bank which closed its stores in June and to negotiate with Russian companies over energy supplies this winter.
