BEIRUT — President Bashar Assad of Syria will speak Sunday in a rare address to the nation, state media said, as rebels fighting to topple his embattled regime pressed ahead with an offensive on the capital.

The official SANA news agency said in a brief statement Saturday that Assad will speak about the latest developments in Syria. The speech would be the first by the leader since June, and comes amid intense fighting between government troops and rebels on the outskirts of Damascus.
