Syrian President Bashar al-Assad rejected peace talks with his enemies on Sunday, Jan 6 in a defiant speech that his opponents described as a renewed declaration of war, Reuters reported.

Although the speech was billed as the unveiling of a new peace plan, Assad offered no concessions and even appeared to harden many of his positions. He rallied Syrians for "a war to defend the nation" and disparaged the prospect of negotiations.

"We do not reject political dialogue ... but with whom should we hold a dialogue? With extremists who don't believe in any language but killing and terrorism?" Assad asked supporters who packed Damascus Opera House for his first speech since June.

"Should we speak to gangs recruited abroad that follow the orders of foreigners? Should we have official dialogue with a puppet made by the West, which has scripted its lines?"

It was his first public speech to an audience in six months. Since the last, rebels have reached the capital's outskirts.

George Sabra, vice president of the opposition National Coalition, said the peace plan Assad put at the heart of his speech did "not even deserve to be called an initiative".

The speech was seen by many as a response to U.N. mediator Lakhdar Brahimi, who has been meeting U.S. and Russian officials to try to narrow differences between Washington and Moscow over a peace plan. Brahimi also met Assad in Syria late last month.
