BEIRUT (Reuters) - Forces loyal to President Bashar al-Assad tightened their siege of rebels in a strategic town on Friday, in a counter-offensive that is shifting the balance of the Syrian war ahead of a peace conference next month.
Rebels said they had managed to infiltrate new fighters into the town of Qusair on the Lebanese frontier, where they are encircled by Assad's army and his allies in Lebanon's Hezbollah militia who have openly joined the war on his behalf.
