Iran has launched a barrage of ballistic missiles towards Israel, triggering explosions across the country.
The Israeli military has intercepted a significant number of missiles, but some have hit central and southern areas.
Israel has warned Iran that the attack will have consequences, and paramedics have reported minor injuries from shrapnel in Tel Aviv.
Iran's Revolutionary Guards claim the attack is retaliation for recent killings of Hezbollah and Hamas leaders, and threaten further attacks if Israel retaliates.
