A second round of face-to-face negotiations between Iran and the United States is being discussed, The Associated Press reported Monday.

The fresh talks could also take place as early as Thursday, according to the report.

Citing officials familiar with the matter, the report said the talks would aim to secure a deal to end the six-week war before the ceasefire expires April 21.

A diplomat from one of the mediating countries said Tehran and Washington have agreed in principle to hold the talks.

It is unclear whether the same level of delegation would attend, according to the diplomat and U.S. officials.

Islamabad, Pakistan, is also being considered again as a potential host, while Geneva is also under discussion, officials said.
