Iran live updates: Trump agrees to continue talks with Iran, but says ceasefire is 'OVER'

Qatari mediators travelled to Iran in an effort to get negotiations between the U.S. and Iran back on track and encourage deescalation form both sides, aources told ABC News.

Iran’s semi-official Tasnim news agency reported that a Qatari delegation had visited Iran on Friday. Flight data indicates that the Qatari delegation has now left Iran after spending several hours on the ground.

After a call between the Egyptian and Qatari foreign ministers, Qatar’s foreign ministry released a statement which stressed “the need for all parties to commit to dialogue and diplomacy, and to implement what was agreed upon within the framework of the Memorandum of Understanding between the United States of America and the Islamic Republic of Iran, including ensuring freedom of navigation in the Strait of Hormuz.”

The U.S. and Iran continue to engage in technical negotiations on nuclear issues, a U.S. official said Thursday, following two days of retaliatory strikes against Tehran this week.

"The United States is still committed to finding a resolution, and technical talks continue. Iran can never possess a nuclear weapon, the official said.

The 60-day ceasefire and memorandum of understanding, the official added, are "performance-based" and Iran’s actions "constitute failed performance at an unacceptable level."

"Iran’s attacks on these innocent vessels are acts of terrorism" the official added.

The head of Iran's railway company said Thursday that one of Mashhad railway lines that was damaged in the overnight U.S. strikes has already been reconstructed "in less than 15 hours" after it was hit, and train traffic has resumed on the line.

According to Iranian state TV, the head of the railway company added that the second damaged line will be reconstructed within the next few hours.

Israeli Prime Minister Benajmin Netanyhau said the country will remain in southern Lebanon for "as long as necessary to ensure the security of our communities in the north."

"If we had not acted at the time we did, and with the intensity with which we did – Iran would have armed itself with nuclear weapons to destroy Israel, that is their plan, and the citizens of Israel would have been in danger of mass death," Netanyahu said while speaking at a pilots' graduation ceremony on Thursday.

"That is why we embarked on these operations with our American friends – to ward off the threat of immediate annihilation, and also a great danger to the entire Western world," Netanyahu said.
