New Delhi, Jan 11 (Agencies): In a snub to Pakistan, Government on Tuesday ruled out sharing of information on the probe into the Samjhauta Express bombing a day after Pakistan sought an update, saying it was "too premature" at this stage.

Ministry of Home Affairs has informed the Ministry of External Affairs to convey to Islamabad that the National Investigation Agency (NIA) has not completed its probe into the 2007 explosions in the India-Pakistan train service which claimed 68 lives.

"It is too pre-mature to share any information with anyone at this stage. The investigation is still on. When it is completed, we will take an appropriate decision," a government official said reacting to Pakistan's insistence on sharing information about the probe.

Reacting to India’s stand, Pakistan Foreign Office Spokesman Abdul Basit termed the Samjhauta Express blast as the biggest conspiracy and said various elements were involved in it, including "Indian terrorists network".

“We want to discuss all strategic issues with India which were included in composite dialogues such as Kashmir, Terrorism, Siachin, Economic, Cultural issues etc," he added.

Yesterday, India's acting Deputy High Commissioner G V Srinivas was summoned to the Pakistan Foreign Office in Islamabad and told that information on progress in the probe should be provided by New Delhi "at the earliest".

The development took place in the wake of right wing activist Swami Aseemanand's reported confession about the involvement of Sangh activists in the attack, in which most of the victims were Pakistanis.

The NIA today announced a cash reward of Rs 10 lakh each for information leading to the arrest of Sandeep Dange and Ramchandra Kalsangra in connection with the Samjhauta Express blasts case.

Besides the two, the NIA has also announced a cash reward of Rs 2 lakh for the arrest of Ashok, also wanted in connection with the same case.

Swami Aseemanand, who has been arrested in connection with the case, has in his confession statement before a magistrate named Dange and Ramchandra as being instrumental in carrying out a number of blasts in the country including in the train.

Pakistan has asked India several times in the past two years to apprise it of developments in the investigation.

Pak insensitive on terror: Krishna

Ahead of a meeting between the Foreign Secretaries, India on Tuesday said it is ready to go "more than half way" in normalising ties with Pakistan if it is "more sensitive" towards New Delhi's "core concern" of terrorism.

"We are looking forward for Pakistan to be more sensitive towards our basic core concern. The core concern is terrorism and terrorism has to be tackled effectively," External Affairs Minister S M Krishna said, adding it cannot be "shoved under the carpet."

Asserting that India wants friendly relationship with Pakistan, he said Islamabad has to fulfil its assurance of dismantling the terror infrastructure operating from its soil for having fruitful talks.
