Cairo: Three Qatari diplomats were killed in a car accident on Saturday while travelling to Egypt’s Red Sea resort city of Sharm el-Sheikh, Egyptian health officials said.

According to the officials, two other diplomats were injured when their vehicle overturned about 50 kilometres (31 miles) from the city.

The diplomats, part of Qatar’s protocol team, were on their way to Sharm el-Sheikh ahead of a high-level summit marking a ceasefire in the Israel-Hamas war in Gaza, the officials said. They spoke on condition of anonymity as they were not authorised to speak to the media.

Qatar has been a key mediator in the ceasefire negotiations, working alongside Egypt and the United States. Turkey also joined the talks earlier this month in Sharm el-Sheikh, which concluded with an agreement for a ceasefire and the release of hostages and hundreds of Palestinian prisoners.

The upcoming summit in Sharm el-Sheikh will be co-chaired by Egyptian President Abdel-Fattah el-Sissi and US President Donald Trump, the Egyptian presidency confirmed in a statement.

More than two dozen world leaders, including French President Emmanuel Macron, Spanish Prime Minister Pedro Sánchez, and United Nations Secretary-General António Guterres, are expected to attend the gathering, the statement added.
