Ethiopian Civil War (ongoing): Up to 600,000 dead, up to 100,000 last year alone.
Russo-Ukrainian war: Around 200,000 dead, up to 95,000 this year.
Insurgency in the Maghreb: Up to 400,000 dead, around 14,000 this year.
Myanmar civil war: Up to 210,000 dead, at least 15,000 this year.
Yemeni civil war: More than 380,000 dead and 85,000 of those were just kids starving to death from 2015 to 2018.
Those conflicts all took place over years. The Israel war on Gaza is blowing through the roof the rate of civilian deaths, the level of indiscriminate targeting of civilians and infrastructure, and the amount of bombings of a small populated area. The conflicts you mention are largely Civil Wars and I am assuming total deaths of the conflict (as you do not share any sources). The War on Ukraine by Russia also has over the entire course of the conflict only had 10,000 civilian deaths according to the United Nations.
On average, nearly 300 people have been killed each day since the start of the conflict, excluding the seven-day ceasefire, data from Gaza’s Hamas-run health ministry indicates. The World Health Organization’s regional emergency director Richard Brennan says he considers these casualty figures trustworthy.
The pace of killing in this war has been “exceptionally high”, says Prof Michael Spagat, who specialises in examining death tolls in conflicts around the world, such as the 2003 Iraq war, Colombia’s civil conflict, wars in the Democratic Republic of Congo as well as previous wars between Israel and Gaza. Within the series of Gaza wars stretching back to 2008, the current one is unprecedented both for the number of people killed and for the indiscriminateness of the killing," he adds.
Each conflict is unique in the way it is fought, but the experts the BBC has spoken to agree that the rate of killing in Gaza is significantly bigger than in others fought recently. "What we’re seeing in terms of civilian deaths has already far outpaced rates of harm from any given conflict we have documented," said Emily Tripp, director of Airwars, an organisation which has monitored civilian deaths in wars and conflicts since 2014.
The former Pentagon intelligence analyst Marc Garlasco said: “To find a similar density of high explosives used in a small populated area, we might have to go back to the Vietnam war for a comparable example - like the 1972 Christmas bombing, when some 20,000 tons of bombs were dropped on Hanoi during Operation Linebacker II.” An estimated 1,600 Vietnamese civilians were killed in the Christmas bombings.
By contrast, US-led coalition air and artillery strikes killed fewer than 20 civilians per day, on average, during the four-month offensive to drive IS out of the Syrian city of Raqqa in 2017, according to Amnesty International.
And an Associated Press investigation suggested that between 9,000 and 11,000 civilians were killed in the nine-month battle between US-backed Iraqi forces and IS for the Iraqi city of Mosul which ended in 2017. This amounts to an estimated fewer-than-40 civilian deaths per day, on average. Mosul had an estimated population of less than two million people when IS captured the city in 2014.
During the almost two years of the Ukraine war, the United Nations estimates that at least 10,000 civilians have been killed.
