More than 20,000 people have been killed in the Gaza Strip in the war between Israel and Hamas, according to the Gaza Health Ministry.

Hamas militants led an attack on Israel on Oct. 7 that killed more than 1,200 people, according to Israeli officials. Israel’s response — an all-out bombardment of Gaza and a ground invasion — has killed almost 1 in 100 people in the Strip.

The Gaza Health Ministry said early Friday that 20,057 Palestinians have been killed in Israeli strikes since Oct. 7.

The number of deaths is far higher than in any conflict in Gaza in recent history. And it is higher than the estimated 15,000 Palestinians killed in the violence that followed the 1948 Arab-Israeli war, according to the Palestinian Central Bureau of Statistics. Palestinians call that mass displacement the Nakba, or “the catastrophe.”
