The BBC has verified footage showing the aftermath of an Israeli attack on Sunday in the north Tehran neighbourhood of Tajrish Square. After the strike, more verified video shows water flooding the area, with water pipes and sewage systems burst. Columns of smoke can also be seen in the Iranian capital.

The warning came on the fourth day of the conflict, when the Israeli military claimed it had achieved air superiority over the Iranian capital and could fly over the city without facing major threats.

Four days into their war with Iran, Israelis are shaken and anxious, yet remain resilient, still backing Prime Minister Benjamin Netanyahu's decision to confront a longstanding foe.
