Meeting between Turkish and US leaders comes just days after Trump's decision to arm Kurdish YPG fighters in Syria. Turkish President Recep Tayyip Erdogan has held talks on a range of bilateral issues at the White House with US President Donald Trump. The main two topics on Tuesday's agenda were Trump's decision to send weapons to Syrian Kurdish forces of YPG and Turkey's request for the extradition of Fethullah Gulen, a US-based Muslim leader.
Gulen, who has lived in Pennsylvania since 1999, is accused by the Turkish government of having planned the failed military coup in 2016. The US announced on May 10 that it would supply weapons and military equipment to YPG units of the SDF alliance battling the Islamic State of Iraq and the Levant (ISIL, also known as ISIS) group in Syria, despite strong opposition from Turkey, a NATO ally.
The Kurdish elements of the SDF, which is backed by the US-led coalition, are from the YPG, or the Kurdish People's Protection Units, the main faction battling ISIL.
"We will support Turkey in the fight against ISIS and the PKK and we will ensure that they have no safe quarter in the region," Trump said at Tuesday's joint news conference with Erdogan.

"We should never allow those groups to manipulate the religious and ethnic structure of the region making terrorism as a pretext or excuse."
Turkey says the YPG is linked to the Kurdistan Workers' Party (PKK) inside Turkey, which has waged an armed campaign since 1984 that has killed more than 40,000 people.
To supply weapons to Kurdish units in Syria is "unacceptable", Turkey's deputy prime minister said in a TV interview. The Pentagon says the YPG is "the only force on the ground that can successfully seize Raqqa in the near future". For its part, Turkey is demanding that the Raqqa offensive is carried out with the Free Syrian Army and not the SDF.
International news media quoted Erdogan as saying before boarding the flight to Washington, DC: "We are either strategic allies and decide together, or we are not, and then we have to go our separate ways." Al Jazeera's Patty Culhane, reporting from Washington, DC, said Erdogan insisted that he reserves the right to fight "terrorism" in the region on all fronts. "This meeting will have a direct impact on the conflict in Syria and the Syrian people," she said. Marwan Bishara, Al Jazeera's senior political analyst, said: "So far, President Trump doesn't really have a clear foreign policy in the Middle East, so Erdogan wishes clarity, engagement and cooperation.
"There's a lot of discord, but there is also a chance that the two like-minded people [
