Here’s the latest.

The US and Iran have conflicting views on whether to hold a second round of talks in Pakistan to end the war. President Trump announced that US negotiators would attend talks mediated by Pakistan, but Iranian state media said no meeting had been confirmed. A two-week ceasefire between the US and Iran is set to expire this week. The Strait of Hormuz remains closed, with Iran maintaining its grip on the waterway crucial to global energy supplies. Pakistan is preparing for the talks, with Islamabad going on a security lockdown and deploying 10,000 extra security forces. The last round of negotiations ended without a breakthrough, and hopes for an immediate agreement have been dampened by Iranian leaders' denial of Trump's claims that they had assented to nearly all of his demands on the country's nuclear program.
