Kurdish militants tighten grip on Syria's northeast. -Al Yarubiya border post.

AMMAN - Kurdish militants moved on Sunday to consolidate their control of an oil-producing region in northeastern Syria after seizing a border crossing with Iraq from Islamist rebels, activists said.

Militia linked to the Kurdistan Workers Party (PKK), which has fought the government of neighboring Turkey for decades, were clearing pockets of resistance of the al-Qaida-linked Islamic State of Iraq and the Levant, al-Nusra Front, and Ahrar al-Sham in the border town of Yarubiya, Syrian opposition sources said.
