HONG KONG (AP) _ Fog shrouded Hong Kong for a second day Sunday, disrupting flights and stranding thousands of people at the airport, the government reported.

Poor visibility delayed 104 flights Sunday and forced 42 to be canceled. A spokesman said that since the fog rolled in Saturday, more than 300 flights had been delayed, canceled or diverted to other cities.

Airport officials said about 8,000 people were waiting there, while other passengers were at nearby hotels.

Trying to clear the backlog of flights, authorities lifted a ban on flying after 1 a.m. The government had imposed the curfew to curb noise.

The Hong Kong Observatory said the fog was expected to continue for the next few days. It said visibility was as low as one-quarter mile.
