Trump's plan to arm Kurds against ISIS may irk Turkey
US President Donald Trump has approved a plan to supply arms to Kurdish YPG forces to support an operation to retake the ISIS stronghold of Raqqa in Syria, the Pentagon said.
The move is expected to anger Turkey, a major US ally, which views Kurdish forces terrorists.
The development comes ahead of Turkish President Reccep Tayyip Erdogan meeting with Trump in Washington next week.
Trump approves plan to arm Kurds against ISIS
Why Turkey opposes US's support for Kurds
Turkey considers the Kurdish YPG militia the Syrian extension of its home-grown Kurdish PKK militant group, which has fought a bitter separatist insurgency since 1984.
The US's support for the YPG has strained relations and the latest development "gets to the heart of Turkish security priorities," said Turkey expert Bulent Aliriza.
"You've now got a question mark over the US-Turkish security relationship," he added.
Pentagon - Arming Kurdish militia "necessary" for victory against ISIS
The US has for long supplied arms to the predominantly Arab Syrian Democratic Forces (SDF), of which the ethnic Kurdhish YPG militia are a part.
The Pentagon said arming Kurdish is "necessary to ensure a clear victory" in Raqqa, ISIS's de facto capital in Syria.
An official said the Kurdish officials will receive small arms, ammunition, machine guns, armored vehicles and engineering equipment.

Turkey calls US decision to arm Syrian Kurds 'unacceptable'
Turkey has called US President Donald Trump's decision to arm Kurdish YPG militia in Syria against ISIS "unacceptable."
Turkey has called on the US, a major ally, to reverse its decision.
President Recep Tayyip Erdogan said the fight against ISIS jihadists shouldn't involve "another terrorist group."
He said he'd express Turkey's worries when he meets Trump in the White House on Tuesday.
Why the alliance with NATO-member Turkey matters
The US-Turkey alliance has been decisive in countering ISIS in Syria. The Incirlik air base in Turkey has provided an invaluable site for the US-led coalition launching airstrikes in ISIS-held territories. However, the decision to arm Kurdish forces could strain the US-Turkey alliance.
