The United Nations nuclear watchdog said on Wednesday it would hold a second round of talks with Iran over nuclear plants.

A senior team from the International Atomic Energy Agency (IAEA) returned earlier on Wednesday after three days of talks in Tehran. The IAEA later released a statement saying a new meeting would take place on Feb 21-22 in the Iranian capital.

"The Agency is committed to intensifying dialogue. It remains essential to make progress on substantive issues," IAEA Director General Yukiya Amano said.
