Syrian rocket attack on Aleppo kills 20

A rebel-held district in Aleppo, Syria.

Amateur video which Reuters is unable to independently verify, purports to show the aftermath of a Syrian army rocket attack in which at least 20 people were killed.

Another 25 were reported missing.

Locals sort through the rubble looking for bodies.

The missile was identified from its remains as a Scud-type rocket that government forces have increasingly used in areas under opposition control.

One activist said the rocket brought down three adjacent buildings in the Jabal Badro neighbourhood at the city's eastern edge.

Syria has been in the throes of an uprising and civil war for almost two years, with an estimated 70,000 people killed.

U.N. investigators say war crimes, including deliberate attacks on civilians, have been committed by both sides.
