Syrian air force jets bombed the rebel-held town of Al-Bab in northern Syria on Monday, killing at least 18 people, according to Syrian activists.
Over the summer, the rebels gained control of a number of towns and villages along the Syrian-Turkish border. Now, those places are being bombarded from the air and from the ground by government forces.
Azaz, in northern Syria's Aleppo province, is one of these places. There, the tombstones in the old section of the town's cemetery are laid out in neat rows.

Syria's president has vowed to crush the rebels by any means; his air force has not spared the towns and villages that support rebel brigades. In August, the death toll often topped 250 a day, according to Syrian activists. The fighting between troops loyal to President Bashar Assad and rebel forces has also sparked a refugee crisis for Syria's neighbors as thousands flee to the borders.
