Thousands of Palestinian refugees have been forced to flee a camp in the Syrian port of Latakia amid shelling by government troops, the UN says. A spokesman for the United Nations Relief and Works agency (Unrwa) told the BBC that more than 5,000 of the 10,000 refugees were on the move. He added that at least four people had died, urging immediate access to the site. Some 30 people have reportedly died in Latakia in a three-day military attack. Syria says it is tackling gangs. On Monday, there were also reports of a clampdown in the capital Damascus, with people being arrested randomly in the Jobar district.
