AMMAN - The Syrian army, backed by Russian jets, escalated bombing of the last rebel bastion on the eastern outskirts of Damascus as they prepared to break a siege of an army base encircled by opposition forces, residents and witnesses said on Wednesday.
They said the army was amassing elite forces to prepare for a major assault on the Military Vehicles Administration, which is besieged by rebels. At least 200 troops were believed to be trapped within its sprawling, heavily defended grounds.
