Pakistan has announced it will soon host talks between the US and Iran, although there was no immediate word from the two nations.

It was also unclear in the announcement on Sunday whether the talks would be direct or indirect.

“Pakistan is very happy that both Iran and the US have expressed their confidence in Pakistan to facilitate the talks,” foreign minister Ishaq Dar said in a televised speech after top diplomats from Turkey, Egypt and Saudi Arabia met in Islamabad.

“Pakistan will be honoured to host and facilitate meaningful talks between the two sides in the coming days.”

Pakistan later said the diplomats had departed for their home countries. The talks were originally scheduled to continue on Monday.

Pakistan’s foreign ministry did not answer questions, and Iran’s mission to the United Nations declined to comment.

Pakistan has emerged as a mediator, having relatively good ties with both Washington DC and Tehran.

Pakistani officials have said their public effort follows weeks of quiet diplomacy, while providing few details.

Meanwhile, Iran’s parliament speaker, Mohammad Bagher Qalibaf, dismissed the talks in Pakistan as a cover after some 2,500 US marines trained in amphibious landings arrived in the Middle East.

He said Iranian forces were “waiting for the arrival of American troops on the ground to set them on fire and punish their regional partners forever,” according to state media.
