Dozens of people have been killed in the ongoing military assault on the central Syrian city of Homs, according to activists.

Opposition groups say at least 6,000 people have died since the anti-government uprising began 11 months ago.

With Syria's makeshift hospitals unable to keep up with the growing rate of casualties, many of the wounded are left with little choice other than to travel to Jordan.

Al Jazeera's Nisreen el-Shamayleh reports from the Jordanian capital, Amman, on those Syrians seeking treatment across the border, including a one-time Olympian.
