Rebels fighting Syrian government have seized control of a southern town near the border with Jordan after four days of battles, the Syrian Observatory for Human rights reported on Wednesday.
The ancient city of Bosra is listed as a UNESCO world heritage site.
Bosra’s historic sites include an ancient citadel built around a 2nd century Roman amphitheatre.
The town was once the capital of the Roman province of Arabia, according to the UNESCO website.
The Observatory said 21 insurgents had been killed in the four days of battles. The Syrian military on Monday said it had killed several insurgent leaders during the fighting.
The Syrian army and allied forces including the Lebanese group Hezbollah launched a big offensive against Syrian rebels southwestern corner early last month. It is an area of strategic importance due to its proximity to Damascus and neighbouring states Israel and Jordan.
