DUBAI — Three Iranian military personnel were killed in south-east Iran early Wednesday when the vehicle they were traveling in was struck by a roadside bomb, Iranian media said. The reported killings — near to where the borders of Iran, Pakistan and Afghanistan meet — come at a time of heightened tension in the region. Heavily-armed drug smugglers are also active in the region. The three men were part of an engineering division of the Islamic Revolutionary Guard Corps (IRGC) working on construction projects near the city of Saravan, Tasnim news agency quoted an unnamed provincial official as saying. — Reuters
