President Donald Trump on Thursday voiced confidence that the hostilities between India and Pakistan would end soon, saying he has some 'reasonably decent' news with the US involved in trying to help reduce tensions between the two nuclear-armed neighbours.

In his opening statement at a news conference at the end of his second summit with North Korean leader Kim Jong-un in Hanoi, Trump said the US has some 'reasonably attractive news' from Pakistan and India.

'We have been involved in trying to help them (India and Pakistan) stop and we have some reasonably decent news,' he told the reporters.

'I think hopefully that (tensions) could be coming to an end, it has been going on for a long time,' Trump said.

Tensions have escalated between India and Pakistan after the Pulwama attack by Pakistan-based Jaish-e-Mohammad in which 40 CRPF personnel were killed on February 14.

India said it had carried out an airstrike against the biggest training camp of Jaish-e-Mohammad in Balakot, Pakistan on Tuesday. Pakistan on Wednesday claimed it shot down two Indian fighter jets over Pakistani airspace and arrested a pilot. India has admitted that a MiG-21 Bison pilot is missing.
