A senior Russian lawmaker says that Russia could expand arms sales to Iran and revise the terms of U.S. military transit to Afghanistan if Washington launches a strike on Syria.

Alexei Pushkov, the Kremlin-connected chief of the foreign affairs committee in the lower house of parliament, told lawmakers that Russia hopes the U.S. will back Russia's proposal for Syria to put its chemical weapons under international control for their subsequent dismantling.

During Wednesday's debate of a draft resolution on Syria, Communists called for an increase in Russian weapons supplies to Iran and a revision of conditions for transit via Russia of supplies for U.S. forces in Afghanistan.

Pushkov said action now would be premature, but warned that if the "party of war" prevails in Washington, Russia should consider those moves.
