GENEVA (Reuters) - Any U.S.- or Turkish-backed attack on Islamic State in the Syrian city of Raqqa would be illegitimate unless coordinated with President Bashar al-Assad's government, the Syrian chief negotiator at peace talks in Geneva said on Friday.
Bashar al-Ja'afari said countries backing rebel groups in Syria, such as Britain, France, Turkey and Qatar, were sponsors of terrorism, and said that a recent rebel offensive was designed to disrupt peace talks in Geneva and Astana.
"All the terrorist attacks, as I said, are pushing everybody towards a total failure and fiasco in the political and diplomatic process," he told reporters, adding that his delegation would never walk away from the talks.
