WASHINGTON, April 10 (Xinhua) -- U.S. President Donald Trump said the outcomes of negotiations with Iran will be clear "in about 24 hours," the New York Post reported Friday.

Trump made the remarks in a phone interview with the news outlet shortly after Vice President JD Vance left Washington for talks with Iran in Islamabad, Pakistan.

"We're going to find out in about 24 hours. We're going to know soon," Trump said, threatening that U.S. warships are being reloaded to resume strikes on Iran if peace talks in Pakistan fail.

"We have a reset going," he said. "We're loading up the ships with the best ammunition, the best weapons ever made -- even better than what we did previously and we blew them apart."

"If we don't have a deal, we will be using them, and we will be using them very effectively," Trump threatened.

The United States, Iran and Israel have all claimed victory in the war. Analysts believe the current ceasefire is fragile and that competing interests and long-standing differences would make it difficult to reach a permanent peace deal in the upcoming negotiations.

On the U.S. side, the talks are expected to focus on Washington's demands that Iran hand over an estimated 1,000 pounds of deeply buried enriched uranium and reopen the Strait of Hormuz to international shipping, according to the New York Post.

Iran's Parliament Speaker Mohammad Baqer Qalibaf on Friday demanded a ceasefire in Lebanon and the release of Iran's blocked assets prior to the commencement of negotiations with the United States. Foreign Minister Seyed Abbas Araghchi has also called on the United States to fulfill its commitments under the ceasefire regarding the necessity to stop Israel's attacks against Lebanon, the official news agency IRNA reported.  ■
