Military officials say Pakistan has test fired a nuclear-capable ballistic missile less than a week after India also test-launched a long-range missile.
The military said the test of the Shaheen 1-A, an intermediate-range missile capable of reaching targets in India, was successful.
Defence experts say that while the exact range of the Pakistani missile has not been revealed, it is it capable of hitting targets up to 2,500 to 3,000km away - putting arch-rival India well within reach.
Pakistan's last test was last month, when it launched the short-range nuclear-capable Abdali missile.
The missile tested today landed in the sea, the military said.
It is a version of the Shaheen-1 - with improvements in range and technical capabilities - and is able to carry nuclear and conventional warheads.
The military say that the missile - which successfully hit its target in the Indian Ocean - further consolidates and strengthens Pakistan's deterrence abilities.
