Israel and Iran have begun a new round of attacks, as the conflict between the two heavily armed rivals enters its fourth day.

The Israel-Iran conflict has escalated into its fourth day with mounting casualties, widening attacks, and no sign of diplomatic resolution.

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.
