Supporters of Syrian President Bashar al-Assad threw stones and tomatoes at U.S. ambassador Robert Ford and other U.S. diplomats who were visiting an opposition figure in Damascus on Thursday, a witness and diplomatic sources said, Reuters reported.
"Two embassy cars were damaged. The U.S. delegation is still there and the crowd is surrounding the building," said the witness.
The witness said the diplomats were visiting Hassan Abdelazim, a centrist politician who has been demanding an end to a crackdown on a six month pro-democracy uprising as a condition for any talks with Assad.
