Syrian president Bahar al-Assad's regime is reportedly tightening control of its borders with fresh landmines, aid workers and fleeing refugees have told UK newspaper The Independent. The Syrian army is said to be laying new mines along the 330km long border with Lebanon to replace those washed away during winter flooding and removed by activists. "We have heard that now that the weather has turned sunny the army has been replanting the mines," said Hassan al-Sabeh, the Lebanon country manager for Islamic Relief.
