Permanent Secretary Mark Sedwill said the UK was "on track" to meet David Cameron's target of receiving 1,000 Syrian refugees by Christmas. "There are a series of charter flights over the next few weeks in order to meet that objective."
Almost three million people have fled across Syria's borders to escape the Syrian civil war that has engulfed the country. The daily flow of men, women and children has become one of the largest forced migrations since World War Two. Deraa - the starting point of the uprising - Homs and Aleppo have seen most people flee.
New arrival refugees to the UK will be given a five-year visa, after which they will be able to apply for leave to remain.
