Iran is ready to engage in talks on its nuclear program with the United States, but only if Washington takes meaningful steps to rebuild trust, a senior Iranian diplomat said Thursday, ahead of a key meeting with European officials.

Iran said it would continue nuclear talks with European powers after "serious, frank, and detailed" conversations on Friday, the first such face-to-face meeting since Israel and the U.S. bombed Iran last month.

Iranian diplomats have met their counterparts from the UK, Germany, and France for nuclear talks, for the first time since Israel launched attacks on Iran's nuclear facilities in June. The strikes triggered a 12-day war, which also saw the US bomb a number of Iran's nuclear sites, bringing US-Iran nuclear talks to an abrupt end.
