Senior UN nuclear watchdog officials left an Iranian diplomatic mission in Vienna after around five hours of talks on the Islamic state's disputed atomic activities on Monday, May 14 declining any comment to media waiting outside, The Jerusalem Post reported.

The team led by Herman Nackaerts, deputy director general of the International Atomic Energy Agency (IAEA), was driven away in a black van shortly after 3 p.m. (1300 GMT). It was not clear whether they would return later on Monday.

The talks, to deal with the IAEA's concerns about possible military dimensions to Iran's nuclear program, had originally been scheduled to continue on Tuesday.
