ISLAMABAD - Pakistan yesterday blamed India of nuclearising the Indian Ocean with the recent test of first nuclear-powered ballistic missile submarine.

At his weekly news briefing here, Foreign Office spokesperson Nafees Zakaria said the nuclear submarine fleet by India was a serious development, which will impact the delicate strategic balance in the region.

“This test resulted in nuclearisation of Indian Ocean, which should be a matter of concern for the region and the international community,” he added.

Earlier, Indian Navy said its first submarine capable of firing nuclear ballistic missiles, the INS Arihant, was undergoing sea acceptance trials and will be commissioned after its completion.

“INS Arihant is now undergoing sea acceptance trails as it had already passed several deep sea diving drills. The submarine will be commissioned after completing all the sea trials,” said HCS Bisht, Vice Admiral of the Indian Navy.

The 6,000-ton vessel is the first nuclear-powered submarine that can launch nuclear-capable missiles manufactured by India – the first nation to announce it has accomplished this feat after the five original nuclear powers. It was built at the Ship Building Centre in Visakhapatnam, one of 13 major ports in India, with some help from Russian specialists and launched in 2009.

The submarine was expected to be commissioned after finishing a round of sea trials in February and participating in the International Fleet Review the same month. On February 23, it was declared ready for operations.

India is currently building 45 new ships at various shipyards around the country, Vice-Admiral Bisht said. Among them are two more Arihant-class submarines.

Zakaria said the Indian side did not notify Pakistan about the submarine-launched ballistic missile.

Asked about recent reports on the security of Indian nuclear arsenals, the spokesperson said all countries should take the requisite steps for the security of nuclear weapons.

He said Pakistan on its part had taken legal, administrative and regularity measures for the security of these arsenals that were at par with the international standards.

About talks with India, the spokesperson said Pakistan was ready to hold talks with New Delhi to resolve all outstanding issues.

On the interference of foreign agents in Pakistan, Zakaria said Pakistan had briefed a number of countries about the sabotage activities of these foreign agents and will continue to raise this issue at every fora.

The spokesperson also raised concerns over increasing human rights violations in the Held Kashmir.

To a question, the spokesperson said the Afghan Chief Executive Abdullah Abdullah was scheduled to visit Pakistan on the second and third of May but the visit has been postponed. “New dates will be worked out through diplomatic channels,” he added.

Zakaria said the process of Quadrilateral Coordination Group was still on and there is desire to bring peace and stability in Afghanistan.
