U.S. President Donald Trump is sending envoys Steve Witkoff and Jared Kushner to Pakistan to take part in a second round of ceasefire negotiations with Iran, the White House said Friday.

Iran Foreign Minister Abbas Araghchi met late Friday with Pakistan Foreign Minister Ishaq Dar and Army Chief Field Marshal Asim Munir shortly after arriving in Pakistan’s capital Islamabad. On Saturday morning Araghchi met with Munir and Pakistan’s Interior Minister Mohsin Naqvi, officials said.

Pakistan also is preparing to receive Witkoff and Kushner for the start of the renewed talks, although officials have not specified when they are due in Islamabad. Vice President JD Vance will not attend, the White House said.

The Trump administration announced it is placing economic sanctions on a major China-based oil refinery and roughly 40 shipping companies and tankers involved in transporting Iranian oil. The move appeared to be part of the administration’s threat to impose secondary sanctions on entities doing business with Iran in order to cut off Iran’s oil exports, a key source of its revenue.

Here is the latest:

Islamabad locked down before talks

Pakistan’s capital Islamabad appeared to be in a near-lockdown Saturday morning, hours after Iran Foreign Minister Abbas Araghchi arrived on a closely watched visit as Pakistan attempts to ease tensions between the United States and Iran.

The weeklong security restrictions have disrupted daily life, with hundreds of thousands of residents struggling to commute even short distances. Checkpoints, road closures and diversions have become routine sights, particularly around sensitive zones.

The usually busy arteries leading to the airport and the heavily fortified Red Zone were largely deserted early Saturday, with movement tightly restricted. Soldiers and police were at key intersections while helicopters circled overhead.

The measures were reinforced over the past 24 hours on the city’s outskirts with additional forces stationed along key airport access routes. Soldiers were visible on rooftops overlooking major approach roads, particularly near the airport where the Iranian delegation arrived late Friday.

Iran executes another man over alleged ties to Mossad

Iran hanged a man Saturday over alleged ties to Israel’s Mossad intelligence agency and his participation in anti-government protests in January.

Erfan Kiani was the latest in a series of executions in Iran following the war and nationwide protests.

The Mizan news agency of Iran’s judiciary announced Kiani was convicted of charges including attacks on security forces in the city of Asfahn in January.
