Iran has launched a rocket into space carrying a test capsule designed to house an animal, amid Western concerns over Tehran's scientific advances. The official IRNA news agency, citing the president's office, said, the Kavoshgar-4 rocket was launched on Tuesday. The capsule is designed to carry a monkey but there were no living creatures on board. Iran had announced it would conduct the launch before the end of Iranian year on March 21.Western powers fear that Tehran could develop a missile capability, masked behind a science programme, that could deliver nuclear warheads. However, Iran denies that its nuclear and space work have military dimensions.
