(dpa) - Iran and the United States are to resume their bilateral talks on the security of Iraq on Thursday in Baghdad, the official Iranian news agency IRNA reported Wednesday.
IRNA reported that that an Iranian delegation arrived in Baghdad Wednesday for the fourth round of talks with the US.
Iran and the US have so far held three rounds of talks but not yet gained any tangible results.
The two countries have had no formal diplomatic relations since US embassy staff in Tehran were taken hostage for 444 days in 1979-81.
Several efforts to improve ties failed and both sides followed a hostile policy in the last three decades, with Tehran branding the US as "Great Satan" and enemy of Moslems worldwide and Washington accusing Iran of sponsoring terrorism in the Middle East, including Iraq.
The Iran-US talks in Baghdad started due the insistence of the Iraqi government which believes that a fruitful cooperation would help ending the chaos in Iraq.
Iranian President Mahmoud Ahmadinejad paid a state visit to Iraq last Sunday and observers had predicted that a positive outcome of the visit would also lead to resumption of Tehran-Washington talks.
