Russia, Syria and Iran have strongly warned the United States against launching new strikes on Syria.

Russian Foreign Minister Sergey Lavrov, who hosted his Iranian and Syrian counterparts at Friday's trilateral meeting in Moscow, denounced last week's U.S. attack on Syria and warned that any further such action would entail "grave consequences not only for regional but global security."

The U.S. has blamed the Syrian government for launching a deadly chemical attack that killed over 80 people and struck a Syrian air force base in response. Russia has claimed that the victims were killed by toxic agents released from a rebel chemical arsenal and pushed for an international probe.

Syrian Foreign Minister Walid al-Moallem welcomed international inspectors to visit the base Washington said served as a platform for the attack.
