MOSCOW/UNITED NATIONS (Reuters) - Russia said on Monday that Western nations had muscled U.N. chief Ban Ki-moon into broadening an investigation into the alleged use of chemical arms in Syria and accused them of trying to use the probe to push President Bashar al-Assad from power.
The United Nations said last week it would investigate Syrian allegations that rebels used chemical arms in an attack near the northern city of Aleppo, but Western countries sought a probe of all claims about the use of such banned arms.
