ISLAMABAD: United States President Donald Trump on Tuesday said he had spoken to Indian Prime Minister Narendra Modi, urging him to avoid a war with Pakistan as he addressed a group of Indian nationals at a Diwali event in the Oval Office in Washington. Nuclear-armed India and Pakistan reached an understanding on May 10 to halt all military actions on land, in the air and at sea in a ceasefire announced by Trump, under which both sides agreed not to escalate hostilities that had spiraled alarmingly in a brief but intense conflict threatening regional peace.
