U.S. President Donald Trump said he expects Iran to comply with what he described as agreed-upon ceasefire terms ahead of scheduled negotiations this weekend, warning that failure to do so could trigger large-scale U.S. military action.

Trump announced that Vice President JD Vance, along with senior envoys Steve Witkoff and Jared Kushner, will represent the United States at peace talks set to take place in Islamabad, Pakistan.

Tensions remain high as Iran continues to assert control over the Strait of Hormuz, warning vessels to seek authorization before transit. Trump cautioned Tehran against imposing tolls on oil tankers moving through the critical waterway, a key global energy corridor.

Iran, for its part, has accused the United States of violating the ceasefire arrangement by allowing Israel to continue military operations against Hezbollah in Lebanon. The White House has rejected that claim, maintaining that Israel’s actions were not covered under the agreement.

Meanwhile, diplomatic efforts are ongoing. According to sources familiar with the matter, the United States is expected to host separate talks aimed at negotiating a ceasefire between Israel and Hezbollah in Lebanon, signaling a broader push to contain regional escalation.
