Dubai, June 30: The United States and Iran on Monday separately announced they will send delegations to Qatar this week, though Tehran insisted it has not agreed to meet with the US “at any level” after attacks across the Persian Gulf over the weekend challenged negotiations to end the war. US President Donald Trump said the Islamic Republic had requested a meeting with US counterparts and that they planned to convene Tuesday in Doha, Qatar. But one of Iran's senior negotiators denied talks had been scheduled.
