DUBAI (Reuters) - Gunmen shot dead a public prosecutor and his driver in south-eastern Iran on Wednesday, Iranian media said, less than two weeks after militants killed 14 Iranian border guards nearby and Tehran retaliated by hanging 16 prisoners.
The killings, in the city of Zabol, near to where the borders of Iran, Pakistan and Afghanistan meet, come at a time of heightened tension in the region as separatist Sunni Islamist militants step up attacks on officially Shi'ite Iran. Heavily armed drug smugglers are also active in the region.
