Blaming 'inadequate' security arrangements for blasts on the Samjhauta Express, Pakistan has said India should complete the probe into the explosions on the train 'as soon as possible' and share the details with it.

Pakistan Prime Minister Shaukat Aziz on Tuesday night said that security arrangements were insufficient for the safety of the train and India should provide concrete security to Pakistanis travelling in the country.

The Indian government should improve train security, state-run APP quoted him as saying at a meeting of the ruling Pakistan Muslim League-Q in Karachi.

The Pakistan prime minister also asked the Indian government to complete the probe launched into the blasts on the train as soon as possible and share the details with Islamabad.

Pakistan government will ensure transportation of bodies of victims belonging to Sindh. The injured will be provided full medical treatment, he said, adding that Air Force planes were ready to bring the injured back home.

Meanwhile, ruling and opposition party members in Pakistan's Senate urged the government to give a 'strong message' to the Indian government, local daily Dawn reported.

Speaking after lawmakers of the opposition and treasury benches expressed concern over reports of Indian agencies' failure to protect the train, Railway Minister Shaikh Rashid said only 13 bodies had so far been identified and 12 of them were being transported from Wagah border.

Earlier, leader of the opposition Mian Raza Rabbani condemned the Indian government's 'inability to provide adequate security for the train.'

Rabbani, a senior leader of the former prime minister Benazir Bhutto-led Pakistan Peoples Party said conflicting statements by officials of Pakistan Railways, Foreign Office and other government officials had created confusion about the exact death toll and the level of Indian government's cooperation in providing credible information.
