From memory, there was a similar incident in China last year; where a flight had an emergency landing and passengers (without a Chinese passport) were kept in the airport terminal overnight, as the airlines didn't organise a temporary visa allowing them to enter the country. Almost expectedly; food, drinks and bathrooms weren't necessary provided, which is how the incident made the news in the usual "worst flying experience" kind of way.
