Islamic State killed 270 in Syrian gas field battle: monitor

Militant group Islamic State killed 270 soldiers, guards and staff when they captured a Syrian gas field on Thursday in the bloodiest clash yet between the al Qaeda offshoot and President Bashar al-Assad's forces, a monitoring group said on Saturday.
The anti-Assad Syrian Observatory for Human Rights reported on Thursday that 90 people had been killed and that many were missing after the attack against the Sha'ar gas field east of Homs in central Syria.
But on Saturday, the Observatory, which monitors violence in Syria through a network of sources in the country on both sides, quoted "trusted sources" as saying that the Islamic State had "killed and executed" 270 people during the assault. It said at least 40 Islamic State fighters were killed in the offensive.
