Israelis and Palestinians 'still need a two state solution' - Biden

Biden said a two-state solution was the only answer to resolving the conflict between the two sides, and pledged to build a major package with other countries to help rebuild Gaza.

Biden, whose administration worked behind the scenes for days to reach a truce, said aid to the region would be coordinated with the Palestinian Authority - Hamas's Western-backed rival in the occupied West Bank - to ensure Hamas was not able to restock its military arsenal.

"Let's get something straight here: until the region says unequivocally they acknowledge the right of Israel to exist as an independent Jewish state, there will be no peace," Biden told reporters at a joint news conference with South Korean President Moon Jae-in.
