Security tight in Hiroshima with leaders set to arrive Thursday for G7 summit

Several world leaders are set to arrive Thursday in Hiroshima for this year's Group of Seven summit. The gathering starts Friday but security is already extremely tight. Up to 24,000 police officers from across Japan will be deployed.

Roads will be temporarily closed Thursday through Monday for the leaders to travel. Bus and tram services to and from the city center are set to be reduced.

A supermarket near the main summit venue has boosted inventory by about 20 percent. Some customers are stocking up on fresh food.

The G7 leaders are scheduled to travel to Miyajima Island to visit Itsukushima Shrine, which is a UNESCO World Heritage Site. Miyajima will be closed to the general public.

After the G7 summit, the leaders of Japan, the US, Australia and India were to meet in Sydney for a Quad framework summit.

But it was cancelled after US President Joe Biden decided not to attend. Biden will go straight back to Washington after the G7 summit to address the US debt ceiling issue.

Arrangements are underway to hold the meeting Sunday while the four leaders are in Hiroshima.
