Syrians fight on as truce deadline passes Damaged building are seen in Taftanaz village, east of Idlib, Syria April 5, 2012. Syrian government shelling and offensives against rebel-held towns killed dozens of civilians across the country on activists said. Syrian President Bashar Assad has accepted a cease-fire deadline brokered by international envoy Kofi Annan, which calls for his forces to pull out of towns and cities by Tuesday and for both government and rebels to lay down their arms by 6 a.m. local time Thursday. DAMASCUS, Syria, April 10 (UPI) -- The deadline for a U.N.-brokered peace plan in Syria passed Tuesday morning with no sign the Assad regime was complying with the deal. Aboard Air Force One en route to West Palm Beach, Fla., White House press secretary Jay Carney said there was no evidence of an end to regime aggression. "Leaders of the Assad regime say a lot of things, make a lot of promises," Carney said. Those promises, overwhelmingly, turned out to be empty. We judge, and the international community judges, the actions of the Assad regime, not their words. We have seen no evidence thus far of any pullback. We have seen much evidence of further brutality and aggression against innocent civilians. Fighting was still reported in several cities, opposition groups said as U.N.-Arab League envoy Kofi Annan was to visit refugee camps in southern Turkey a day after Syrian forces fired across the border near a refugee camp, killed two Syrian refugees and wounded at least 23 other people, including a Turkish police officer and another Turkish citizen, and as Lebanon called on Syria to investigate the shooting death of a cameraman who was reporting on the unrest from the Lebanese side of the border. Carney said Washington was waiting on Annan's report. Annan spokesman Ahmad Fawzi did not say if Annan would visit the camp near the southern Turkish town of Kilis, where the shooting occurred, the Turkish newspaper Today's Zaman reported Tuesday. Sens. John McCain, R-Ariz., and Joseph Lieberman, Ind-Conn., were also to meet with refugees in Turkey Tuesday. Nearly 3,000 Syrians fled to Turkey last week, pushing the total number of refugees to nearly 25,000, Turkish officials said. A senior Turkish Foreign Ministry official told the newspaper Syria's ranking diplomat was summoned and given a harsh message about Turkey's anger regarding the episode. The ministry called the gunfire a "grave" development. The government of Syrian President Bashar Assad had no immediate comment. Turkish President Abdullah Gul and Defense Minister Ismet Yilmaz both said last week a military option had not been ruled out in resolving the Syrian crisis. Turkey was once one of Assad's closest allies. But Prime Minister Recep Tayyip Erdogan became an early and harsh critic of Syria's crackdown on protesters last year. The opposition Syrian National Council umbrella group said it was ready to respect a cease-fire. "The opposition, including the Free Syrian Army, says it will comply if the regime does," council executive committee member Bassma Kodmani was quoted by The New York Times as saying. The Syrian opposition groups were ready to put a cease-fire into effect Tuesday and not wait until Thursday, she said. But she said the regime's actions were "clearly not a sign of their intention to cooperate in good faith." At least 160 people were killed in Syria Monday, as forces loyal to Assad shelled buildings and shot at residents of rebellious cities, opposition groups said. Damascus said Sunday it would not honor the cease-fire worked out by Annan until it received written guarantees from rebel groups that they would stop fighting and written assurances from Qatar, Saudi Arabia and Turkey they would "stop funding and arming terrorist groups."
