World leaders must do “everything possible to prevent” the violence in Israel and Gaza from spilling over into a wider Middle East conflict, Rishi Sunak and the Qatari leader have agreed.The Prime Minister met with the Amir of Qatar in Saudi Arabia on Friday before jetting off to Egypt, the third stop on his tour of the region, part of a diplomatic effort to stop the Israel-Hamas war from escalating.The British leader arrived at around lunchtime in Egypt, where he held talks with president Abdel Fattah El-Sisi.A spokeswoman for the Prime Minister said the UK’s “priority” is to focus on the opening of the Rafah crossing, Gaza’s only border point not controlled by Tel Aviv, to allow humanitarian aid to enter and for British nationals to leave the bombarded territory.
