Indian Prime Minister Narendra Modi used his first conversation with President Donald Trump since the early May conflict between India and Pakistan to express his frustration with Trump’s repeated claims that he played a significant role in brokering a ceasefire between the two nuclear-armed countries.

Prime Minister Narendra Modi and US President Donald Trump held a 35-minute phone call, Foreign Secretary Vikram Misri announced Wednesday. “India has never accepted, does not accept, and will never accept mediation in its bilateral relations with Pakistan,” Modi clarified.
