Syrian forces responded by firing at protesters, killing at least 24 people, activists said, most of them in the central city of Homs, a hotbed of dissent.

"Qaddafi is gone, your turn is coming, Bashar," protesters shouted on Friday in the central city of Hama, long a hotbed of resistance to the regime.

The Syrian uprising has proved remarkably resilient over the past seven months, but has shown some signs of stalling in recent weeks as the government forges ahead with a bloody crackdown that the UN estimates has killed more than 3,000 people.

Although the mass demonstrations in Syria have shaken one of the most authoritarian regimes in the Middle East, the opposition has made no major gains in recent months, it holds no territory and has no clear leadership.

Now the armed uprising in Libya that drove Qaddafi from power appears to have breathed new life into the Syrian revolt.

"Our souls, our blood we sacrifice for you, Libya!" Syrian protesters chanted Friday.

Others held signs linking Assad's fate to those of other deposed Arab leaders. Tunisia's Zine El Abidine Ben Ali has been driven into exile, and Egypt's Hosni Mubarak is in jail and facing charges of complicity in the deaths of more than 800 protesters in his country's uprising.

"Ben Ali fled, Mubarak is in jail, Qaddafi is killed, Assad ... ?" read one banner.

In many ways, the Syrian uprising has taken cues from the Libyans recently. Syria's opposition formed a national council like the Libyans' National Transitional Council, hoping they could forge a united front against Assad that Syrians and the international community could rally behind.

And with the successes of armed Libyan revolutionaries present in their minds, many Syrian protesters say they are starting to see the limits of a peaceful movement.
