Syrian President Bashar Assad's government

The  Syrian government on Tuesday dismissed White House allegations that it was preparing a new chemical weapons attack, as activists reported an airstrike on an Islamic State-run jail in eastern Syria that they said killed more than 40 prisoners.

The Russian military on Oct. 6 strongly warned the United States against striking the Syrian army, noting that its air defense weapons in Syria stand ready to fend off any attack.
The statement underlined high tensions between Moscow and Washington after the collapse of a U.S.-Russia-brokered Syria truce and the Syrian army's offensive on Aleppo backed by Russian warplanes.
