Pakistan has urged the International Court of Justice to dismiss a case filed by the Marshall Islands, a tiny South Pacific state, to force India, Britain and Pakistan to pursue nuclear disarmament.

In a statement issued Thursday, Pakistan's foreign ministry said its nuclear program falls exclusively within its domestic jurisdiction.

Initial court proceedings began Monday, when the ICJ began determining whether it can accept the Marshall Islands' case, which aims to breathe new life into disarmament negotiations.

The island state is still suffering the after-effects of nuclear testing along its territory in the '40s and '50s.

It filed a case against nine countries that have declared or are believed to have nuclear weapons, but only the cases against Britain, India and Pakistan reached this preliminary stage.
