Iran's Revolutionary Guards chief warned the United States and Britain on Saturday that Iran would retaliate with missiles if attacked, state-run television reported.
General Yahya Rahim Safavi also accused US and British intelligence services of provoking unrest in the oil-rich southwestern Iran and providing bomb materials to Iranian dissidents.
Two bombings killed at least nine people in the southwestern city of Ahvaz on January 21, near the border with southern Iraq where 8,500 British soldiers are based.
"The world knows Iran has a ballistic missile power with a range of 2,000 kms," Safavi said on state-run television. Israel is within that range.
"We have no intention to invade any country. We will take effective defence measures if attacked," he said.
