Iran says it "responds to diplomacy with diplomacy, war with firm defense"

Iran "responds to diplomacy with diplomacy war with firm defence", Iranian Foreign Ministry spokesman Abbas Mousavi said on Friday on his Twitter account, reacting to remarks by U.S. envoy on Iran Brian Hook.

Hook said on Friday in a news conference in the Saudi capital Riyadh that U.S. diplomacy did not give Iran the right to respond with military force. Hook said Iran must meet U.S. diplomacy with diplomacy.
