The Palestinian group Hamas is warning that Israel has “started a war” by waging targeted killings on its leadership. Two Palestinian militant leaders were killed in an Israeli strike on a vehicle they were traveling in Tuesday. Agence France Presse is reporting at least ten Palestinian civilian bystanders were wounded in the attack, which took place near the Jabaliya refugee camp in the northern Gaza Strip. A senior Hamas official said: “Israel has started a war with this assassination and it will pay a heavy price.” Hamas has claimed responsibility for the killing of an Israeli soldier today in Jenin.
