20 Militants Killed in Failed Deir Ezzor Airport Attack

At least 20 gunmen of the so-called 'Islamist State of Iraq and the Levant' (ISIL) terrorist group were killed in the second failed terrorist attack in a month to take over an air base in eastern Syria, an opposition monitoring group said Sunday.

The Syrian Observatory for Human Rights said that ISIL tried, starting late Saturday, to storm the air base, and a total of 20 militants were killed in the attack, as well as two Syrian soldiers.

Nineteen of the ISIL members were Syrian, while one was Moroccan. All were killed in fighting and heavy army shelling.

"The withdrawing jihadists seized and took with them several anti-aircraft missiles," said Observatory director Rami Abdel Rahman.

The attack was the second recent attempt by ISIL to take over the Deir Ezzor military air base, one of the last remaining regime positions in the eastern province.

Deir Ezzor is located on the border with Iraq, where ISIL also occupies large swathes of territory.

Activists report it rules the people under its control through a reign of terror.
