DUBAI/CAIRO/LONDON (Reuters) -Israel has informed several Arab states that it wants to carve out a buffer zone on the Palestinian side of Gaza's border to prevent future attacks as part of proposals for the enclave after war ends, Egyptian and regional sources said. According to three regional sources, Israel related its plans to its neighbours Egypt and Jordan, along with the United Arab Emirates, which normalised ties with Israel in 2020. They also said that Saudi Arabia, which does not have ties with Israel and which halted a U.S.-mediated normalisation process after the Gaza war flared on Oct. 7, had been informed.
