A senior ISIS leader and four terrorists were killed by Turkish military and U.S military in two separate incidents.

The Pentagon said on Saturday a senior leader of the terrorist group Islamic State (IS) in Libya was killed in an air strike conducted on Friday night, Xinhua reported.

The US military conducted the airstrike on Friday in Libya targeting Abu Nabil, also known as Wissam Najm Abd Zayd al Zubaydi, an Iraqi national who was a longtime al Qaeda operative and senior IS leader in Libya, a Pentagon statement said.

Calling it the first U.S strike against IS leaders in Libya, the statement said Nabil's death will degrade IS's ability to meet the group's objectives in Libya, including recruiting new IS members, establishing bases in Libya, and planning external attacks on the United States.

Meanwhile, Turkish troops were patrolling along Syrian border in Oguzeli town of southern Gaziantep when they witnessed two vehicles moving towards soldiers with armed insurgents, Xinhua quoted NTV news as saying.

The IS members fired at the Turkish troops after being warned to leave the area, the sources said.
In retaliation, the soldiers returned fire, killing four of the IS terrorists in one vehicle and the other vehicle fled.

Turkey has beefed up security operations against suspected militant targets around the country since 10 October, when two suicide bombings hit the capital of Ankara, killing 102 people and injuring many others.

The air strike operation was authorised and initiated prior to the Paris attack, Pentagon said.
