There was "indisputable evidence" that the Syrian regime had "deliberately murdered civilians" in a massacre in the central village of Traimsah in which more than 200 people died, US Secretary of State Hillary Clinton said Friday. She called for an immediate ceasefire and for UN observers to be allowed to enter the site. A UN source told dpa that Syria "totally ignored" a request by a United Nations monitoring mission to enter Traimsah Traimsah. The request was made by General Robert Mood, the head of the UN team based in the capital Damascus, during a news conference. Mood said his team was ready to go to Traimsah, in the province of Hama, if a ceasefire was established. The UN mission said in a report to international mediator Kofi Annan that al-Assad's forces had used tanks and helicopters in attacking Traimsah, said the source, who asked dpa not to be named. Mood told reporters he had information from his team in Hama that fighting has been raging in and around Traimsah since Thursday. Clinton said: "As long as the Assad regime continues to wage war against the Syrian people, the international community must keep increasing the pressure on the regime to halt the violence and allow for a political solution to go forward." She called on the UN Security Council to take strong action and make clear to the Syrian regime there would be consequences for not complying.
