The summit between U.S. President Donald Trump and North Korean leader Kim Jong Un will be on Singapore's southern island of Sentosa, the White House said on Tuesday as preparations accelerated for next week's event.

White House spokeswoman Sarah Huckabee Sanders said in a Twitter post that the venue would be the Capella Hotel on Sentosa and thanked Singaporeans for their hospitality. The summit is scheduled to start next Tuesday morning.

Singapore airspace will be restricted during the summit, a notice to airmen posted by the International Civil Aviation Organization (ICAO) and the U.S. Federal Aviation Administration (FAA) said Wednesday.
