Modi, who visited the residence of Anti Terrorism Squad (ATS) Chief Hemant Karkare who was killed in the attack on Wednesday, said that the nation should join hands in the fight against terrorism.

Holding Pakistan responsible for allowing use of its territory for carrying out the Mumbai attacks, Gujarat Chief Minister Narendra Modi said on Friday that Islamabad has violated the UN code on the use of land and sea routes for launch of terror strikes against India.

"This is for the first time Pakistan has allowed use of sea routes to further terrorism against India," fumed Modi.

He said Pakistan has violated UN convention on use of sea and land routes to launch attacks against India. "Terrorists have targeted US, British and Israeli citizens and made Mumbai a place that has been hit by international terrorism," he said.

Modi claimed that the terrorists had used boats seized from Indian fishermen by Pakistani Marine Police to launch attacks against India.

"I had warned the Centre about the use of such boats to launch terror attacks against us at a meeting of Chief Ministers convened by Prime Minister Manmohan Singh last year," he said.

Modi said he hoped that the Government would raise the issue of its neighbour's actions at appropriate levels diplomatically.

The Gujarat Chief Minister termed as "disappointing" Singh's address to the nation in the wake of attacks in Mumbai.

The country had pinned a lot of hope on the Prime Minister but his address was disappointing, Modi said. He said the terror strikes in Mumbai were an attack on the sovereignty of the nation and asked the people to unite to root out the menace.

Modi asked the Prime Minister to urgently convene a meeting of Chief Ministers to discuss issues of coastal security.
