Iran's Revolutionary Guards have said the country has the capability to build longer-range missiles, but has no need to do so since its current missiles can reach U.S. and Israeli targets.

Iranian state media on Tuesday quoted commander Brigadier General Amir-Ali Hajizadeh as saying Iran's missiles have a maximum range of 2,000 kilometers based on U.S. and Israeli targets in the region.

He said Iran's missile program does not pose a threat to any other nations.

The comments come as Iran fired 14 missiles during the second day of a 10-day missile training exercise. State media have said the exercises are designed to preserve “readiness against enemy strikes.”

The United States and Israel suspect Iran is planning to build nuclear warheads for its missiles. Iran denies nuclear weapons ambitions, saying its missiles are conventional and designed for the nation's protection.
