On May 16, ISIS carried out massive bomb attacks against the Shaer gas field in the Homs province, setting off a minor earthquake in the city of Palmyra and blowing up several of Shaer’s pumping stations. The gas field – one of the biggest in the province – has been the scene of heavy clashes between militants and pro-government forces. The gas field was captured by ISIS on May 5. Separately, the group tried to advance on the T4 airbase.
