The children killed in the conflictpublished at 11:58 British Summer Time 20 May 2021
Of the 230 people killed in Gaza at least 65 are children, according to its health ministry. Of the 12 people killed in Israel, two children are among the dead, the country's medical service says.
Among the children killed in Gaza were sisters Yara, 9, and Rula, 5 from the al-Kawalek family. Both had been receiving treatment for trauma from the Norwegian Refugee Council (NRC).
The al-Kawaleks were polite girls who always did their homework on time, one of their teachers, who did not want be named, told the BBC.
The youngest victim on the Israeli side is thought to be Ido Avigal, a five-year-old boy killed last Wednesday in the southern town of Sderot.
Ido was killed inside a fortified room in what the Israeli military described as an "incredibly rare" incident.
Rocket shrapnel pierced the protective metal plating used to cover the window of the room he was in, also injuring his mother and seven-year-old sister. He died of his injuries hours later.
