Islamic State fighters have executed "dozens" of Syrian soldiers fleeing Tabqa military airport in the north, a monitor said Thursday, with the jihadists boasting on Twitter they had killed 200 troops.
"Dozens of Syrian soldiers captured while fleeing... after the IS overran Tabqa airbase were executed by the jihadists during the night," said Rami Abdel Rahman, head of the Syrian Observatory for Human Rights monitoring group.
The jihadists seized the airport on Sunday after weeks of bitter fighting with loyalist forces, cementing their control over Raqa province, capital of their self-declared Islamic "caliphate".
