On April 14, sources in Pakistan told Xinhua that it remains uncertain whether the next round of negotiations between the United States and Iran will still take place in the Pakistani capital, Islamabad. Earlier, Reuters reported, citing four sources, that US and Iranian delegations would return to Islamabad for talks later this week. Subsequent updates cited officials from the Iranian embassy in Pakistan stating that the two delegations might hold negotiations as early as this week or early next week. Reports indicated that the Iranian delegation has reserved time from the 17th to the 19th. Some Pakistani media reported earlier the same day that the US-Iran talks would restart on the 16th in Islamabad. US media also reported that if negotiations continue, locations such as Geneva, Switzerland, are being considered. The US and Iranian delegations held talks in Islamabad on the 11th, which concluded on the morning of the 12th without reaching any agreement. (Xinhua)
