Syrian President Bashar al-Assad said his government receives information about U.S.-led airstrikes against Islamic State militants in Syria, but he stressed there is no direct cooperation.
Assad told the BBC in Damascus that there are exchanges of messages through third parties, such as Iraq, but the exchanges do not include tactical information.
He said Syria would not join the U.S.-led coalition.
"No, definitely we cannot and we don't have the will and we don't want, for one simple reason: because we cannot be [in] alliance with the country who support the terrorism," Assad said.
