Efforts underway for second round of US-Iran talks

The standoff between the United States and Iran deepened on Tuesday. Pakistan said it was racing to bring the sides together for more talks.

Meanwhile, the US declared it had blockaded Iran's ports, Tehran threatened to strike targets across the region.

Though last week's ceasefire appeared to hold, the showdown over the Strait of Hormuz risked reigniting hostilities and deepening the region-wide war's economic fallout.

Talks aimed at permanently ending the conflict - which began Feb. 28 with US and Israeli strikes on Iran – failed to produce an agreement last weekend, though Pakistan has proposed hosting a second round in the coming days.

Two Pakistani officials, who spoke on condition of anonymity because they weren't authorized to discuss the matter with the media, said that the first talks were part of an ongoing diplomatic process rather than a one-off effort.

Two US officials, who spoke on the condition of anonymity to discuss sensitive diplomatic negotiations, said on Monday that discussions were still underway about a new round of talks. They said that the venue, timing and composition of the delegations hadn't been decided, but that talks could happen on Thursday.

The war, now in its seventh week, has jolted markets and rattled the global economy as a great deal of shipping has been cut off and airstrikes have torn through military and civilian infrastructure across the region.

The fighting has killed at least 3,000 people in Iran, more than 2,000 in Lebanon, 23 in Israel and more than a dozen in Gulf Arab states. Thirteen US service members have also been killed.
