Iran rejected a call Tuesday by three European countries urging it to refrain from any retaliatory attacks that would further escalate regional tensions. Iran calls it an “excessive request.”

The leaders of Britain, France and Germany in a joint statement Monday asked Iran and its allies to refrain from retaliation for the killing of Hamas political leader Ismail Haniyeh in Tehran last month. Iran has blamed Israel.

The European leaders also endorsed the latest push by mediators Qatar, Egypt and the United States to broker an agreement to end the Israel-Hamas war. Talks are expected to resume Thursday. And they called for the return of scores of hostages held by Hamas and the “unfettered” delivery of humanitarian aid to Gaza.

Mediators have spent months trying to get the sides to agree to a three-phase plan in which Hamas would release the remaining hostages captured in its Oct. 7 attack in exchange for Palestinians imprisoned by Israel, and Israel would withdraw from Gaza.

After more than 10 months of fighting, the Palestinian death toll is nearing 40,000 in Gaza, according to the Health Ministry there.
