Poonch, Oct 12 (ANI): Indian army conducted mock drill in Poonch sector in Jammu and Kashmir to avoid any casualty during ceasefire violation by Pakistan. India and Pakistan exchanged gunfire across the Kashmir frontier on Saturday. Pakistani troops heavily shelled 15 border out posts and hamlets along the International Border overnight, leaving three persons injured, one of them seriously in Jammu district. After nine days of attacking each other with mortars and heavy machine guns, the two armies abruptly stopped fighting on Thursday night (October 09), although their governments kept up the war of words blaming the other of launching unprovoked fire. Poonch has reported 10 injuries and a death during the cross-border firing. Meanwhile, as part of the mock drill, the army instructed villagers to wait for a siren, after which they should immediately evacuate roads and hide behind solid structures.
