DUBAI, United Arab Emirates (AP) — Iran’s top diplomat said the possibility of new negotiations with the United States on his country’s nuclear program has been “complicated” by the American attack on three of the sites, which he conceded caused “serious damage.”

U.S. strikes on Iranian nuclear sites inflicted "serious and significant damage," Iran has acknowledged for the first time since the attack nearly a week ago.

President Donald Trump said during a NATO meeting he planned to meet with Iranian officials after bombing their nuclear military facilities.

Trump spent his final day at NATO disputing intelligence that said U.S. strikes on Iran's nuke facilities set the country back only by months.

President Donald Trump returned from a NATO summit overseas days after he made the decision to launch U.S. strikes on Iranian nuclear sites and as he says both Israel and Iran violated a ceasefire he announced.

Iran’s Supreme Leader Ali Khamenei claimed victory over Israel on Thursday in his first public statement since a ceasefire was declared in the war between the two countries
