Thousands of Palestinians in Israel demonstrated against Syrian President Bashar Assad on Friday, calling for him to step down and end his violent suppression of a nationwide revolt.
Chanting "Bashar Assad leave" and "Let the people live", protesters in the northern town of Kafr Kanna set fire to posters of the Syrian president.
Assad has shown no sign of easing his campaign to stamp out an 11-month uprising against his rule. His forces on Friday resumed attacks on opposition strongholds in the city of Homs, which has now been under fire for two weeks.
The United Nations says more than 5,400 civilians have been killed in the uprising and the UN General Assembly on Thursday told Assad to stop the violence and surrender power.
Syrian authorities say they are fighting foreign-backed "terrorists".
Israeli Defense Minister Ehud Barak said Thursday he expected Assad to fall "within weeks".
Last month Israel's army chief Lieutenant-General Benny Gantz said the country was preparing to take refugees from Assad's minority Alawite sect into the Golan Heights, in the event of the president's downfall.
Israel captured the Golan Heights from Syria in the 1967 Middle East war. Despite the fact that the two countries have never made peace, the Golan frontier has largely been quiet.
The army said in a statement that forces of the Kurdish People's Protection Units (YPG) had fired on pro-Ankara rebels close to the rebel-held town of Azaz in northern Syria late Tuesday.

"It's regrettable that the citizens of the countries on the list have never participated in any act of terrorism against the US and yet they are being punished for acts of terrorism by citizens of other countries which are not on the list," said Zarif.
"We consider such threats against the Syrian leadership to be unacceptable," Kremlin spokesman Dmitry Peskov told journalists.
The White House said the preparations were similar to those undertaken by the Assad regime ahead of an apparent chemical attack on a rebel-held town in April.
