Pakistan's military conducted a training launch of a surface-to-surface missile weapons system on Saturday, it said in a statement, upping tensions with arch-rival India.

New Delhi has blamed Islamabad for backing an attack on tourists last month in Indian-administered Kashmir, sparking a ramping up of rhetoric between the nuclear-armed neighbours.

"Pakistan today conducted a successful training launch of the Abdali Weapon System -- a surface-to-surface missile with a range of 450 kilometres," the military said.
