British special forces in Afghanistan intercepted an Iranian shipment of 48 122mm rockets to the Taliban that, according to western diplomats, would have enabled the group to double the range of its attacks to 12 miles. The rockets were discovered on February 5, 2011, when British and Afghan troops stopped a convoy in Nimruz Province in south-west Afghanistan. According to one official, an examination of the rockets showed that they were recently manufactured, but had been tampered with to conceal their Iranian origin.
