U.S. urges de-escalation in Syria after series of retaliatory strikes

The United States opposes any military action that destabilises the situation in Syria, a State Department spokesperson said, amid an escalation in retaliatory strikes by Turkey and a Kurdish militia along the Syrian border.

Separately, Russia called on Turkey to show restraint in its use of "excessive" military force in Syria and to keep tensions from escalating, Russian news agencies cited a Russian envoy to Syria as saying on Tuesday.
