DAMASCUS, Syria (AP) -- Syrian President Bashar Assad says British airstrikes in Syria against the Islamic State group are illegal and doomed to fail.
Assad said in an interview with Britain's Sunday Times that IS cannot be defeated with airstrikes alone unless there is coordination with forces on the ground.
His comments were carried by Syrian state news agency SANA on Sunday.
British warplanes began launching airstrikes in Syria on Thursday after Parliament voted to authorize air attacks against IS targets there.
Assad has said the only airstrikes that have worked against IS are those carried out by Russia, which is cooperating with Syrian government forces.
Syrian troops have captured areas from IS since Moscow began its air campaign on Sept. 30.
