Anti-U.S. billboards in Tehran not approved, ordered to be taken down

TEHRAN, Oct. 27 (UPI) -- Anti-American billboards have been collected from Tehran after government officials ordered them to be taken down, government spokesman Hadi Ayazi said.

The billboards were installed without the consent of the city's cultural center, Ayazi told the state-run Islamic Republic News Agency.

The collection of the posters comes as Iran and the United States experience a thaw in their relations, CNN reported.

U.S. President Barack Obama and Iranian President Hassan Rouhani have expressed their willingness to negotiate an agreement to deal with Iran's nuclear program.
