Regime forces seized a military base from rebels in southern Syria on Tuesday and were locked in heavy fighting in a nearby opposition stronghold, a monitor and state media said, according to AFP.

Government troops captured the Brigade 82 base outside Sheikh Miskeen in Daraa province and were clashing with rebels inside the town, state news agency SANA said.

The Syrian Observatory for Human Rights also reported the advances, saying army forces backed by fighters from Lebanon's Hezbollah movement and air strikes were engaged in fierce fighting with rebels. The Britain-based monitoring group said regime forces seized the base a day after taking the northern part of the town.
