Syrian President Bashar Assad on Sunday outlined a new peace initiative that includes a national reconciliation conference and a new government and Constitution but demanded regional and Western countries stop funding and arming rebels first.

Mr. Assad ignored international demands for him to step down and said he is ready to hold a dialogue with those “who have not betrayed Syria.”

Syrian opposition forces, including rebels on the ground, are likely to reject Mr. Assad’s proposal. They have repeatedly said they will accept nothing less than the president’s departure, dismissing any kind of settlement that leaves him in the picture.

“We are in a state of war. We are fighting an external aggression that is more dangerous than any others, because they use us to kill each other,” he said.

Mr. Assad was speaking on Sunday in a rare address to the nation, his first since June 2012. He spoke to a packed hall at the Opera House in central Damascus, and the audience frequently often broke out in cheers and applause.

Wearing a suit and tie, the President spoke before a collage of pictures of what appeared to be Syrians who have been killed since March 2011.

The Internet was cut in many parts of Damascus ahead of the address, apparently for security reasons.

As in previous speeches, Mr. Assad said his forces were fighting groups of “murderous criminals” and jihadi elements and denied that there was an uprising against his family’s decades-long rule.

“The first part of a political solution would require regional powers to stop funding and arming (the rebels), an end to terrorism and controlling the borders,” he said.

“We never rejected a political solution... but with whom should we talk? With those who have extremist ideology who only understand the language of terrorism?” he said.

“Or should we with negotiate puppets whom the West brought. ... We negotiate with the master not with the slave.”

As in previous speeches and interviews, he clung to the view that the crisis in Syria was a foreign-backed agenda and said it was not an uprising against his rule.

“Is this a revolution and are these revolutionaries? By God I say they are a bunch of criminals,” he said.
