Shelling hit school killing 6 in rebel-held Syrian village

Syrian government forces shelled a rebel-held village in the country's northwest on Wednesday, hitting a school and killing at least six people, opposition activists said.

The attack in Idlib province, the last rebel stronghold Syria, was part of an ongoing offensive in which Syrian troops have captured more than 40 villages and hamlets over the past two weeks.

Idlib is dominated by al-Qaida-linked militants and is also home to 3 million civilians. The United Nations has warned of the growing risk of a humanitarian catastrophe in the region, which lies along the Turkish border.

A war-monitoring group, the Britain-based Syrian Observatory for Human Rights, said a teacher and four students were killed in Sunday's government shelling of the village of Sarmin.

Hadi Abdullah, an Idlib-based opposition activists, gave a slightly higher death toll, saying seven people were killed, including a woman and four children. Different death tolls are common in the immediate aftermath of bombings.

Syrian troops have been bombarding parts of Idlib since last month, with the shelling and airstrikes intensifying since the ground offensive began on December 19.

The UN Office for the Coordination of Humanitarian Affairs said that as a result of hostilities, more than 235,000 people had been displaced between December 12 and December 25.

Many of them have fled from the town of Maaret al-Numan, toward which the Syrian troops have been steadily advancing.

Elsewhere in northern Syria, a car bombing on Wednesday in the town of Suluk, controlled by Turkey-backed opposition fighters, killed three people, according to Syrian state media and the Observatory.

Areas controlled by Turkey-backed fighters have witnessed several explosions, with dozens killed and wounded in the past weeks. Turkey has blamed Syrian Kurdish fighters for the attacks. They deny the charges.
