LONDON: Britain's foreign office on Friday updated its travel guidance to tell its citizens in Gaza to follow Israeli advice and relocate to southern Gaza within the next 24 hours.

"The Israeli military announced on the morning of 13 October that the entire population of Gaza north of Wadi Gaza should relocate to southern Gaza within the next 24 hours," the update posted on the government website said.

"We advise following this advice issued by the Israeli authorities. We recognise this is a fast-moving situation that poses significant risks." (Reporting by William James; Editing by Kate Holton)
