Army on Friday foiled an infiltration bid from across the Indo-Pak border by killing three militants at Kupwara district of north Kashmir, a defence spokesman said here.
He said a heavily armed group of militants entered Machhal sector, 150 km from here, in the wee hours but were confronted by alert troops guarding the border.
The intruders were asked to surrender but they opened fire and in the retaliatory action, the three militants were killed, he said.
The operation was still on, he added.
