Pakistan test-fired a nuclear-capable, surface-to-surface ballistic missile with a range of 2,000 km (1,250 miles) today, Reuters quoted a military official as saying. The test of the Hatf VI (Shaheen II) missile was successful, he said. "It can carry all types of warheads including nuclear," the official said. The Hatf VI is a two-stage solid fuel missile which can carry nuclear and conventional warheads with high accuracy. An advanced version has a potential range of 2,500 km (1,560 miles).
