Iran’s Foreign Minister Abbas Araghchi has told his British counterpart Yvette Cooper in a phone call that any US use of British bases would be seen as “participation in aggression” against the Islamic republic, AFP reports.

It was not clear when the call with Cooper took place.

“These actions will certainly be regarded as participation in aggression and will be recorded in the history of relations between the two countries,” said Araghchi, according to a statement released by the ministry.
