Syria: Rebels Attack Aleppo Intelligence HQ

Dozens of Syrian security personnel and rebels have been killed in an attack on an intelligence facility in the city of Aleppo, a monitoring group says.

The attack began when a bomb placed in a tunnel near Air Force Intelligence's headquarters was detonated, the Syrian Observatory for Human Rights reported.

Islamist and jihadist rebels then launched an attack on the building.

Aleppo has been divided between rebel and government control since fighting erupted in the city in mid-2012.

But soldiers, backed by pro-government militiamen and fighters from Lebanon's Hezbollah movement, have made steady advances since launching an offensive to retake the rebel-held west of the city last year.
