The prosecutor of the International Criminal Court Monday applied for arrest warrants against Israeli Prime Minister Benjamin Netanyahu and top Hamas leaders on suspicion of war crimes and crimes against humanity.
Netanyahu rejected the landmark request "with disgust", while Foreign Minister Israel Katz slammed it as "a historical disgrace that will be remembered forever."
The United States also firmly criticised the prosecutor's move.
Prosecutor Karim Khan said he was seeking warrants against Netanyahu and Israeli Defence Minister Yoav Gallant for crimes including "starvation", "wilful killing", and "extermination and/or murder".
"We submit that the crimes against humanity charged were committed as part of a widespread and systematic attack against the Palestinian civilian population pursuant to State policy. These crimes, in our assessment, continue to this day," said Khan in reference to Netanyahu and Gallant.
US President Joe Biden called the application "outrageous" and Secretary of State Antony Blinken denounced it as "shameful".
"Whatever this prosecutor might imply, there is no equivalence -- none -- between Israel and Hamas," Biden said in a statement.
The charges laid against the Hamas leaders including Yahya Sinwar, the head of the movement in Gaza, and Ismail Haniyeh, the movement's political chief, include "extermination", "rape and other acts of sexual violence", and "taking hostages as a war crime".
"We submit that the crimes against humanity charged were part of a widespread and systematic attack against the civilian population of Israel by Hamas and other armed groups pursuant to organisational policies," said the statement.
Khan alleged that the two Hamas leaders -- plus Mohamed Deif, who heads Hamas's armed wing -- were "criminally responsible for the killing of hundreds of Israeli civilians" during the attacks of October 7, 2023.
Hamas said it "strongly condemns" the ICC prosecutor's application for arrest warrants against its leaders -- but said it supported the ICC's move against Netanyahu and Gallant.
South Africa, which led international efforts to brand Israel's assault on Gaza a genocide, welcomed the arrest warrant requests and said the law must "be applied equally to all".
ICC judges will now decide whether the application meets the threshold for the warrants to be formally issued -- a process that could take some weeks or even months.
If granted, the warrant means that technically any of the 124 ICC member states would be obliged to arrest Netanyahu if he travelled there.
But while the warrant could complicate some travel for Netanyahu, the court has no mechanism to enforce its warrants, relying on its members to play ball.
Opening its doors in 2002, the ICC is the world's only independent court set up to probe the gravest offences including genocide, war crimes and crimes against humanity.
