Manmohan Singh addresses media representatives in New Delhi, July 18, 2006

Indian Prime Minister Manmohan Singh says India will have to review its relations with Pakistan after last week's Mumbai blasts, but that he is not shutting the door to the peace process.

On his way back from the G-8 summit in Russia, Mr. Singh told reporters he will not describe it as a setback, but that the ongoing two-and-a-half-year peace process has suffered.

Although an investigation is still on, India has said it suspects that Lashkar-e-Toiba, a Pakistan-based Kashmiri militant group, carried out the bombings that left nearly 200 people dead.

In Islamabad, President Pervez Musharraf warned Tuesday that it would be playing into terrorists' hands to delay the peace process with India because of the train attacks.

He spoke at a National Security Council meeting in Islamabad. Later, a ministry statement quoted him as saying India and Pakistan must not allow such terrorist acts to undermine the historic opportunity for lasting peace.

India postponed the official-level talks scheduled for this week to review progress in the peace process, saying the atmosphere is not conducive because of the blasts.
