Israel troops and tanks fight Hamas in streets as airstrikes pound Gaza

Gazans are cut off from the world and also each other, under a total siege and a communications blackout as the war enters a new phase. Israel’s military says it bombed 150 underground targets in northern Gaza, and has again urged residents there to move south. Hamas, which the UK has designated a terrorist organisation, said its fighters have clashed with Israeli troops in Beit Hanoun and the Bureij refugee camp. Warning, this report contains distressing images.
