IAEA: Tehran Asked Talks Be Delayed to February 8

Didn't say why

The U.N. nuclear watchdog said on Tuesday a planned meeting with Iran next week to discuss steps meant to ease concerns over its nuclear program has been pushed back to February 8 at Tehran's request.

The International Atomic Energy Agency did not say why Tehran asked for a delay. But the original date, January 21, is just a day after Iran and big powers are to start implementing an interim deal on curbing Iranian nuclear activity, suggesting a busy agenda in coming days may have led to the postponement.
