The Middle East is the closest it has been to regional war in 50 years, according to Saudi Arabia's ambassador to the UK. Prince Khalid bin Bandar al Saud expressed concern over the worsening situation on the ground and called for renewed efforts to stop the fighting, particularly in Gaza. He emphasized the global impact of the Israeli-Palestinian conflict and urged both sides to take responsibility and prevent further escalation. The ambassador's warning comes as Israel's defence minister announced a 'new phase' of the war, with troops moving to the northern border amid speculation of a more serious attack.
