The Palestine Red Crescent Society said on Monday that 15 medics and rescuers killed by Israeli forces last month in Gaza were shot in the upper body with "intent to kill".Israeli army chief Lieutenant General Eyal Zamir meanwhile ordered a more in-depth investigation into the attack after an initial probe was completed by the military.The killings occurred in the southern Gaza Strip on March 23, days into a renewed Israeli offensive in the Hamas-ruled territory. They have since sparked international condemnation, with Israel insisting there were militants in the ambulances.The PRCS announcement came as Hamas and rescuers said an Israeli strike on southern Gaza killed one journalist and wounded nine others.The journalist is one of at least 12 people killed in Israeli strikes across the Palestinian territory yesterday, according to Gaza's civil defence agency, as the war entered its 19th month.Younis Al-Khatib, president of the Red Crescent in the Israeli-occupied West Bank, told journalists in Ramallah that an autopsy of the humanitarian personnel slain in March revealed that "all the martyrs were shot in the upper part of their bodies, with the intent to kill".He called for an international probe into the killings."We call on the world to form an independent and impartial international commission of inquiry into the circumstances of the deliberate killing of the ambulance crews in the Gaza Strip," Khatib said.Army chief Zamir has instructed a deeper investigation to be conducted and completed in the coming days, the military said in a statement."The preliminary inquiry indicated that the troops opened fire due to a perceived threat following a previous encounter in the area."A video recovered from the cellphone of one of the slain aid workers, released by the Red Crescent, appears to contradict the Israeli military's account.The footage shows ambulances travelling with their headlights on and emergency lights flashing.Eight staff members from the Red Crescent, six from the Gaza civil defence agency and one employee of the UN agency for Palestinian refugee were killed in the incident.Their bodies were found buried near the site of the shooting in the Tal al-Sultan area of Rafah city, in what OCHA described as a mass grave.**************Leaders of Egypt,France, Jordan holdphone call withTrump over GazaThe leaders of Egypt, France and Jordan held a phone call with US President Donald Trump yesterday to discuss the need to reach a ceasefire in Gaza and release hostages, the Egyptian presidency said in a statement.400,000 displaced: UNNearly 400,000 Gaza residents have been displaced in the weeks since Israel resumed military operations in the territory, with relentless attacks leading to "large-scale civilian casualties," the UN secretary-general's spokesman said yesterday. Survivors across Gaza are being displaced repeatedly and forced into an ever shrinking space where their basic needs just cannot be met," said spokesman Stephane Dujarric.
