 And just an update, do we know how many people have been killed for sure at the moment? We know that the Gaza Health Ministry says 17 were killed in El Mawassi, and we don't have an official number for this school strike, but the reports from the ground say possibly 12. Okay, well, thank you very much for the very latest there. That's the BBC's Barbara Plett-Usher in Jerusalem with the latest on that report coming from Gaza.
