A mortar fired by Iranian forces today killed a man in Panjgur district of Pakistan's south-western Balochistan province. Commissioner of Makran, Bashir Bangulzai said that the mortar shell landed on a vehicle, instantly killing a resident of Washuk and causing extensive damage nearby. <br/><br/>The attack came a week after Iranian border guards fired five mortar shells into Pakistani territory. There is tension between the two countries since April 26 when 10 Iranian border guards were killed in a militant attack near the border. Iran accused that militants hiding in Pakistan were involved in the attack.
