"Pakistan today carried out another successful test-fire of its indigenously developed medium range surface-to-surface ballistic missile Hatf IV/Shaheen 1," a military statement announced.

The tests "reflect Pakistan's resolve and determination to continue to consolidate its minimum deterrence needs and national security."

The three tests since October 3 coincide with India's formalisation of a deal with Israel to buy the billion-dollar Phalcon airborne early warning radar system. The deal was signed on Friday.

Pakistan has long complained of an arms imbalance with its rival nuclear neighbour and has expressed alarm over the Phalcon purchase.

President Pervez Musharraf told Malaysia's New Straits Times newspaper that Pakistan would "counter" India's acquisition of the Phalcon system.

"They have reached an agreement and we will counter it. That has to be very clear," he said in comments picked up in Pakistani newspapers Tuesday.

Foreign Minister Khurshid Mahmud Kasuri warned on Saturday that Islamabad would "exploit all our resources to maintain this balance," saying Pakistan was deeply concerned about India's arms acquisitions.

The Shaheen 1, which was also tested last Wednesday, can carry any type of warhead up to 700 kilometers (434 miles), which means it can send a nuclear payload deep into India.

Tuesday's test was conducted as a follow-up to last week's Shaheen 1 test "to validate certain additional parameters," the military statement said.

"These parameters stand completely validated in the light of data collected from the test."

The latest test "concludes for now" the series of tests which began on October 3 with the launch of the short-range Ghaznavi missile, or Hatf III, which can carry a nuclear warhead 290 kilometers (180 miles).

"The longer-range version of the Hatf series will be tested in future as soon as technical parameters need to be validated," the statement said, without specifying when.

The latest three tests are the first since peace moves between Pakistan and India began in April, only to have again stalled.

In March Pakistan test-fired its short-range Abdali missile, the same day that India test-fired its own short-range Pirthivi missile.
