A series of recent deadly airstrikes on school buildings sheltering displaced people in Gaza were part of a deliberate Israeli military bombing strategy, with further schools identified as targets, the Guardian has learned.

At least six school buildings have been struck, reportedly killing more than 120 people, in recent months as part of a targeting effort by the Israeli military.
