Explosions have again been heard in locations across Tehran, as darkness fell in Iran's capital. Earlier the United States and Israel stepped up their attacks on Iranian cities, including Karaj and Isfahan, where eyewitnesses described bodies lying in the street. Also, President Trump has said he needs to be personally involved in selecting Iran's next leader.

The United States and Israel have carried out a sixth day of attacks.

We'll also investigate unconfirmed reports that the US is trying to foment a Kurdish rebellion in the north of Iran.
Also in the programme: people in Nepal have been voting for the first time since last year's "Gen Z" demonstrations, in which dozens of young protesters died; and the drug trials that have had some terrific results for children with the severest epilepsy.
