The U.S. and Iran will likely return to Pakistan next week for a second round of peace negotiations, two senior Pakistani officials told MS NOW on Wednesday.

The latest sign of the countries’ continuing efforts to reach a diplomatic end to the war came from officials who are involved in finalizing decisions with the U.S. and Iranian teams, but did not want to be named because of sensitivities around negotiations, MS NOW reported.

The step toward resuming the stalled peace talks came as tensions in the Persian Gulf continued to rise, further imperiling a shaky two-week ceasefire between the U.S. and Iran.

Oil tanker traffic through the Strait of Hormuz remains at a trickle as Iran continues to pose threats to passing vessels and the U.S. enforces a retaliatory blockade of Iranian ports.

President Donald Trump, who said last week that the ceasefire agreement was subject to the strait being fully reopened, had complained about the lack of activity in the vital shipping route prior to announcing the blockade.
