Pakistan Foreign Minister Khursheed Mehmood Kasuri arrives in India today to resume peace talks a day after the bombing of an India-Pakistan train.
Suitcase bombs exploded on a train connecting New Delhi to the northern Pakistani city of Lahore, sparking a fire yesterday that raked through two carriages and killed 66 people.
The attack appeared to be an attempt to undermine a peace process between the two nuclear rivals.
Rather than the finger-pointing that has often quickly surfaced after past attacks, however, both governments condemned the bombings and the prime ministers of the two countries phoned each other yesterday.
Pakistan President Pervez Musharraf said: "We will not allow elements which want to sabotage the ongoing peace process to succeed in their nefarious designs."
Although the attack occurred in India, most of the victims in the Samjhauta Express were Pakistanis.
One person in one of the two coaches that caught fire was detained in connection with the midnight explosion on the train, about 80 kilometres north of New Delhi, it was reported.
Many newspapers have criticised what they said were security lapses that allowed bombers to board what is meant to be one of the best guarded trains in India.
