BBC: Syrian rebels have captured a military air base near the northern city of Aleppo, activists say. Fighters took control of al-Jarrah base after days of clashes there with security forces, reports said.

The reported capture comes a day after rebels in the north-east overran Syria biggest hydro-electric dam, delivering a strategic blow to the government. Turkey's prime minister meanwhile has said a deadly blast at a crossing with Syria was caused by a car bomb.

At least 10 Syrians and three Turkish nationals died on Monday in the explosion at the Cilvegozu customs post on the Turkish side of the border, in the southern province of Hatay. "A vehicle loaded with bombs was able to reach our customs gate because the customs gate on the Syrian side is not working and is not being controlled," Tayyip Erdogan was quoted by AFP news agency as saying.
