Heavy fighting breaks out in Aleppo

Heavy clashes erupted on March 5 between Syrian regime forces and rebels near an intelligence headquarters the opposition had tried to seize in a spectacular attack, a monitor and security source said.
“There are very heavy battles between regime forces and (rebel) fighters in the area of yesterday’s attack, with the two sides shelling the other,” Rami Abdel Rahman, the director of the Britain-based Syrian Observatory for Human Rights, said.
Meanwhile, at least 18 civilians were killed in a single regime barrel bomb attack in Syria’s northern city of Aleppo , the monitoring group said.
The group said the bomb, dropped from a helicopter, struck an eastern sector of the divided city where people were gathering to buy and sell fuel.
The clashes came after rebels launched a major attack on the air force intelligence headquarters in western Aleppo on Wednesday, leaving at least 20 members of regime security forces and 14 rebels dead.
A Syrian military source confirmed the “ongoing clashes” in the area after “a fierce attack was launched by the army this morning against (rebel) gunmen positions, killing and wounding many of them.”
The attack on the intelligence offices — a frequent target of the rebels — began with a huge explosion in a tunnel that caused part of the building to collapse. An assault by anti-regime gunmen followed but was repelled by security forces.
