Pakistan’s military says it has successfully launched an intermediate - range ballistic missile capable of carrying a nuclear warhead."Pakistan today conducted a successful launch of the intermediate range ballistic missile Hatf IV Shaheen-1 Weapon System," the military said in a statement on Wednesday. The statement added that nuclear-capable missile, with a range of 900 kilometers, was fired from an undisclosed location and landed in the sea. The test came four days after India successfully test fired a nuclear-capable Agni II missile from eastern Odisha state. The surface-to-surface missile strike can reach targets around 2,000 kilometers away. India and Pakistan have routinely carried out missile tests since both demonstrated nuclear weapons capability in 1998. The two neighbors have engaged in an arms race since the partition of Pakistan from India in 1947. Both neighbors have refused to sign the nuclear Non-Proliferation Treaty (NPT) and other international regulatory pacts that restrict developing or testing nuclear weapons. India considers the NPT as discriminatory, while Pakistan has indicated that it will not join the international treaty until its neighbor does so.
