The New York Times reports:
Western nations expelled senior Syrian diplomats on Tuesday in a hardened and coordinated condemnation of the weekend massacre of more than 100 villagers in Syria, nearly half of them children.
The response by the United States and others came as the top United Nations peacekeeping official gave new credence to suspicions that pro-government Syrian thugs, known as shabiha, were at least partly responsible for the killings, despite official Syrian denials of complicity. ...
The effort by countries including the United States, Britain, France, Germany, Bulgaria, Australia, Spain, Italy and Canada to expel the senior Syrian diplomatic officials appeared timed to underscore the extreme isolation of the Syrian government and pressure Mr. Assad into honoring the terms of a nearly two-month-old peace plan negotiated by Mr. Annan.
