Syrian Rebels May Lose Control of Key Haven at Border Town

Could spell an end to the two-year-long rebellion

A battle raging for control of a border town critical to the supply of men and arms to opponents of the regime of Syrian President Bashar Assad may determine whether the two-year rebellion will survive, say analysts and a rebel officer.

Rebels have held the town of Qusayr a few miles from Lebanon for over a year, but fighters for Iran-backed Hezbollah, a U.S.-designated terror group, have added renewed strength to the Syrian government offensive to crush the rebel haven.
