A group of several hundred Syrians from two besieged towns arrived outside Damascus Tuesday after passing through Turkey and Lebanon as part of a rare UN-backed deal to evacuate people from flashpoint areas, AFP reports.

A source close to the deal confirmed the arrival of over 300 people from the government-controlled towns of Fuaa and Kafraya in northwestern Idlib province to the Sayyida Zeinab area south of the capital.

An official celebration to welcome the arrivals was expected later Tuesday, the source said.
