DUBAI (Reuters) - A fourth round of nuclear talks between Iran and the United States is likely to take place over the weekend in the capital of Oman, with Iranian state media pointing to May 11 as a probable date.

DUBAI (Reuters) -Iran remains committed to diplomacy with the United States, the government said on Monday, after a fourth round of nuclear talks with Washington due in Rome on May 3 was postponed for "logistical reasons".

Omani mediators said it was a small technical issue, Iran said new negotiations would soon be announced, and Washington acted as if nothing had been scheduled or canceled without explanation.
