listening to russian foreign minister lavrov's news conference on al-jazeera. now the rapid translation makes it a bit garbled. but he seems to have said that the russian plane was "shot down by american planes." that is, f-16s made in the usa. but then he asserted that any action taken with those planes had to be approved by washington. then he said that he just got a call from john kerry, who asked to meet as soon as possible. 'i told him that one more meeting about assad just wouldn't be useful.'
