India's Modi maintains there was no US mediation in ceasefire with Pakistan

India's Prime Minister Narendra Modi maintained in a conversation with US President Donald Trump on Tuesday that a ceasefire with Pakistan after a four-day conflict was achieved through talks between the two militaries and not US mediation.

Trump had said last month that the nuclear-armed South Asian neighbours agreed to a ceasefire after talks mediated by the US, and that the hostilities ended after he urged the countries to focus on trade instead of war.

"PM Modi told President Trump clearly that during this period, there was no talk at any stage on subjects like India-US trade deal or US mediation between India and Pakistan," Indian Foreign Secretary Vikram Misri said in a press statement.

"Talks for ceasing military action happened directly between India and Pakistan through existing military channels, and on the insistence of Pakistan. Prime Minister Modi emphasised that India has not accepted mediation in the past and will never do," he said.

Misri said the two leaders spoke over the phone at the insistence of Trump on the sidelines of the G7 summit in Canada which Modi attended as a guest. The call lasted 35 minutes.

The White House did not immediately respond to a request for comment about the Modi-Trump call.

Pakistan has previously said that the ceasefire happened after its military returned a call the Indian military had initiated on May 7.
