In Syria, a suicide bomber driving a truck packed with 1.5 tonnes of explosives, has killed at least 30 people and wounded dozens in the central city of Hama.
State news agency Sana said Syrian rebels had driven the truck into a government checkpoint on a busy road.
The explosion appears to have set ablaze a nearby petrol tanker, increasing the damage and casualties, the BBC reports.
The UK-based Syrian Observatory for Human Rights said the al-Qaeda-linked al-Nusra Front carried out the attack.
The attack came as the Arab League chief Nabil el-Araby said peace talks aimed at ending the conflict in Syria, would take place next month in Geneva.
Mr el-Araby was speaking after meeting the international envoy on Syria, Lakhdar Brahimi, who is on a tour of the Middle East to prepare for the conference.
