MUNICH -- Pakistani Foreign Minister Abdul Sattar condemned India Saturday for conducting new surface-to-air missile tests -- the second series in less than a week --, saying the move was unwise and unwarranted.

"At a time when a spark can ignite a conflagration, the situation calls for exercise of restraint and responsibility," Sattar told an International Security Conference in the Germany city of Munich.

"India's decision to test-fire two ballistic missiles was both unwise and unwarranted. It deserved international criticism and censure," Sattar said.

India's Defense Ministry said Wednesday it had carried out successful tests on the naval version of its homegrown Trishul (Trident) missile in southern India.

Two of the missiles -- which have a range of nine kilometers (5.6 miles) and are fitted with a 5.5-kilogram (12-pound) fragmented warhead -- were fired during the six-day exercise, the ministry said.

Five days earlier, on January 25, India said it had tested a short-range version of its intermediate, nuclear-capable Agni missile.

The test prompted angry condemnation from Pakistan and raised concerns of a fresh escalation in military tensions between the south Asian rivals.

Pakistan and India have massed over 800,000 troops on their common border following a deadly attack on India's Parliament on December 13 which the Indian government has blamed on two Pakistani militant groups.

On Friday India renewed its call on Pakistan to stop supporting "cross-border terrorism" in the disputed Himalayan state of Kashmir, which is divided between the countries and claimed by both.

Pakistan in turn traded accusations with its neighbor over the kidnapping of a U.S. journalist in the Pakistani port city of Karachi, who his captors claimed to have killed on Friday, AFP reported.
