Turkish Airlines says cancels flights to Arbil due to security concerns

ISTANBUL (Reuters) - Turkish Airlines has cancel led all flights to Arbil, capital of Iraqi Kurdistan, until further notice due to security concerns, a spokesman said on Twitter on Friday. Sunni Islamist militants have advanced to within a half hour's drive of Arbil, prompting a U.S. air strike on Friday, the first such intervention since American troops pulled out in 2011.
