Syrian warplanes bombed a bakery run by Islamic State (IS, also known as Isis) in the city of Raqqa, killing 25 people, in air raids yesterday that also hit a major training camp used by the insurgent group for a second day running, a group monitoring the war said.

The air strikes on Raqqa, Islamic State’s stronghold some 400km northeast of Damascus, also hit a building used as an Islamic court, and another of the group’s offices, the Syrian Observatory for Human Rights said.

Rami Abdulrahman, founder of the Observatory, said the bakery was run by the militant group. The Observatory, which gathers information from all sides in the civil war, said the dead included 12 civilians and nine Islamic State activists.

IS, which has seized wide expanses of territory in Iraq and Syria, drove the last Syrian government forces out of Raqqa province in late August when its fighters seized an air base, capturing and later executing scores of Syrian soldiers.

In a headline bar, Syrian State TV said army units had destroyed weapons and ammunition stores used by Islamic State fighters in Raqqa, the main Syrian foothold of IS.
