Iranian state television says Tehran has launched a rocket with a satellite carrier bearing three devices into space, though it’s unclear if any object entered orbit around the Earth.

The state TV report Thursday did not say when the launch was conducted or what devices the carrier brought with it. It comes amid ongoing negotiations in Vienna over Iran’s tattered nuclear deal. Previous launches have drawn rebukes from the US. Iranian state media has offered a list of upcoming planned satellite launches for the Islamic Republic’s civilian space programme, which has been beset by a series of failed launches. Iran’s paramilitary Revolutionary Guard runs its own parallel programme that successfully put a satellite into orbit last year.
