Egypt condemned statements by Israeli officials suggesting the establishment of a Palestinian state on Saudi territory as "irresponsible" on Saturday.
Egypt's foreign ministry said in a statement the idea was a "direct infringement of Saudi sovereignty" and that the kingdom's security was a "red line for Egypt."
Israeli Prime Minister Benjamin Netanyahu appeared to be joking this week when he responded to an interviewer on pro-Netanyahu Channel 14 who misspoke by saying "Saudi state" instead of "Palestinian state" before correcting himself.
