"We support the arrest warrant. We consider it important that this courageous decision be carried out by all country members of the accord to renew the trust of humanity in the international system," Erdogan said in a speech in Istanbul.

The ICC issued the warrants against the Israeli leaders and Hamas military chief Mohammed Deif on Thursday on charges of crimes against humanity and war crimes in the ongoing war on Gaza.

The warrants accuse Netanyahu and Gallant of crimes against humanity and war crimes in Gaza, including the use of "starvation as a method of warfare," as well as systematic attacks on civilians. 

All 124 states parties to the ICC are now legally bound to arrest Netanyahu and Gallant if they enter their territory. ICC prosecutor Karim Khan urged all members to comply with the arrest warrants.

"It is imperative that Western countries -- who for years have given the world lessons on law, justice and human rights -- keep their promises at this stage," added Erdogan.

Erdogan has become a fierce critic of Israel (and its Western allies) since the start of the Israeli war on Gaza, now in its 13th month.

He has vowed several times to make sure that Israel's prime minister, who has angrily condemned the ICC warrants, is "brought to account" over the brutal assault on the Palestinian territory.

Turkey and 52 other countries this month sent a letter to the United Nations demanding an end to arms sales and deliveries to Israel.
