The United States said on Monday it believed Syrian President Bashar al-Assad was responsible for a chemical weapons attack against civilians last week, and U.S. Secretary of State John Kerry said President Barack Obama was consulting with allies before deciding how to respond.
U.S. warships armed with cruise missiles are already positioned in the Mediterranean.
“We want to strongly warn against any military attack in Syria. There will definitely be perilous consequences for the region,” Iranian Foreign Ministry spokesman Abbas Araqchi told a news conference. “These complications and consequences will not be restricted to Syria. It will engulf the whole region.”
As well as backing Assad, Iran also supports the Lebanese Shi’ite militant group Hezbollah which has sent fighters into Syria to help the government there. Tension is also rising between Hezbollah and Israel over cross-border rocket attacks.
