Amid allegations of bad faith and ceasefire violations from both Washington and Tehran, negotiators arrived in Islamabad for high-stakes talks.

The sides are far apart on Iran’s nuclear program, the Strait of Hormuz and the Israeli campaign against Hezbollah in Lebanon.

Iran accused the U.S. and Israel of violating the truce and threatened to withdraw from negotiations. Israeli attacks in Lebanon were a major point of dispute.

People in Iran say they could be left to pick up the pieces if President Donald Trump destroys the country’s infrastructure and economy.

The president says Iran’s remaining leaders are more reasonable. But assassinations have left in place an emboldened government driving a hard bargain, officials say.

Trump’s statement follows an Iranian report that it had rejected a 15-point U.S. ceasefire proposal, a move that still left the door open for a counteroffer.
