Syria's state-run news agency says two large explosions have struck the southern city of Daraa, causing multiple casualties and heavy material damage.

SANA did not immediately give further information or say what the target of Saturday's explosions was.

The Britain-based Syrian Observatory for Human Rights says the blasts went off near a branch of the country's Military Intelligence in Daraa.

The Observatory, which relies on a network of activists on the ground, says the explosions were followed by clashes between regime forces and rebels fighting to topple President Bashar Assad.
