Turkish troops cross into Syria's Kurdish-held Afrin region:

Turkish troops today crossed over the Syrian border into the Afrin region on the second day of Ankara's operation against the Peoples' Protection Units (YPG) Kurdish militia, Prime Minister Binali Yildirim said.
Yildirim told Turkish reporters in a briefing in Istanbul that the troops crossed into the YPG-controlled region in Syria at 0805 GMT from the Turkish village of Gulbaba, the Dogan news agency reported.
The state-run Anadolu news agency said that the Turkish army troops, whose number was not specified, were advancing alongside forces from the pro-Ankara rebel Free Syrian Army (FSA).
The Dogan news agency published images of tanks and armoured vehicles pushing through grassy terrain.

Turkish forces yesterday began a major new operation aimed at ousting the YPG from Afrin, pounding dozens of targets from the sky in air raids and with artillery.
However this was the first confirmation that Turkish ground troops were now involved in the operation inside Syria.

Yildirim was quoted as saying that the Turkish forces aimed to create a security zone some 30 kms deep inside Syria.
Turkey accuses the YPG of being the Syrian offshoot of the Kurdistan Workers' Party (PKK) which has waged a rebellion in the Turkish southeast for more than three decades and is regarded as a terror group by Ankara and its Western allies.

But the YPG has been the key ally of Turkey's fellow NATO member the United States in the fight against IS jihadists, playing a key role in pushing the extremists out of their Syrian strongholds.
