The Israeli army says 24 of its soldiers were killed in Gaza on Monday – the deadliest day for its forces since their ground operation began.
That includes 21 reservists who died in an explosion likely caused by mines that Israeli forces had placed in two buildings to demolish them, the Israel Defense Forces (IDF) said, with an investigation under way into what happened.
It is thought a missile fired by Palestinian armed fighters hit a tank guarding the troops just beforehand.
