Al-Jazeera Video: Activist in Damascus speaks on the reports of fighting in Mezzeh

"Heavy fighting has broken out between opposition fighters and forces loyal to President Bashar al-Assad in a main district of the Syrian capital Damascus that is home to several security installations, witnesses said.

The sound of heavy machineguns and rocket-propelled grenades echoed throughout the night from the western neighbourhood of al-Mezzeh, one of the most heavily guarded areas of the capital, residents told the Reuters news agency by telephone on Monday.
