AKIPRESS.COM - Syrian or Russian aircraft struck an aid convoy near Aleppo on Monday and killed 12 people, according to a war monitor, as the Syrian military declared a one-week truce brokered by the United States and Russia over, Reuters reports.

The United Nations confirmed the convoy was hit but gave no details on who carried out the attack or how many died as world leaders converged on New York for their annual U.N. gathering under the shadow of fresh violence in the Syrian civil war.

The Syrian Observatory for Human Rights monitoring group said the attacks were carried out by either Syrian or Russian aircraft, adding that there had been 35 strikes in and around Aleppo since the truce ended.

A humanitarian aid group said the death toll was higher. Fourteen Syrian Arab Red Crescent volunteers were killed, Elhadj As Sy, secretary general of the International Federation of Red Cross and Red Crescent Societies, told a U.N. summit.

At least 18 of 31 trucks in a U.N. and Syrian Arab Red Crescent (SARC) convoy were hit along with an SARC warehouse, said U.N. spokesman Stephane Dujarric. The convoy was delivering aid for 78,000 people in the hard-to-reach town of Urm al-Kubra in Aleppo Governorate, he said.
