各方采取行动保证叙利亚停火协议

There are signs the United Nations-brokered cease-fire in Syria is starting to fray, even as efforts are under way to make sure it holds.
　　
Two activist groups and Turkish villagers reported clashes between Syrian troops and rebel forces near the Turkish border Friday. Some of the fighting was reportedly heavy.
　　
The British-based Syrian Observatory for Human Rights said the Syrian government deployed tanks to the northwestern village of Khirbel el-Joz before gunfire erupted. Separately, the Local Coordination Committees reported tank movements and heavy gunfire in nearby Khirbet el-Joz.
　　
Sipan Hasan with the Syrian Center for Democracy Support, a Netherlands-based group, says the fighting is no accident on the part of the Syrian army.
　　
The fighting comes as Syria's opposition forces have called for widespread protests to test the Syrian government's resolve to abide by the truce. Hasan says more than a million people are expected to take to the streets as part of those protests.
　　
Meanwhile, a spokesman for U.N.-Arab League envoy Kofi Annan said the Syrian government has agreed to let an advance team of observers into the country.
　　
Ahmad Fawzi told reporters in Geneva "we have the advance team standing by to board planes and to get themselves on the ground as soon as possible.'' He said he expected the U.N. Security Council the pass the necessary resolution later Friday.
　　
Western nations have been pushing the Security Council to send two waves of observers to Syria to monitor and enforce the cease-fire. A draft resolution calls for Syria to give the observers full and unimpeded freedom of movement across the country. It also demands Syria withdraw troops and heavy weapons from population centers.
