Syrian rebels backed by the Turkish military have seized the town of Nairab in northwest Syria's Idlib province, Turkish and rebel officials said on Tuesday, the first area to be taken back from advancing Syrian government forces.
Syrian President Bashar al-Assad's forces, supported by Russian airpower, are trying to retake the last large rebel-held region in Syria after nine years of war.
Nearly a million Syrians have been displaced by the latest fighting.
U.S. Secretary of State Mike Pompeo slammed the offensive saying the Syrian government will not be able to obtain military victory and that Washington was working with Ankara on how to resolve the crisis but he provided no details.
