LONDON (AP) - Britain's Department for Transport says there is a risk that parts of British airspace could be closed beginning Sunday as the volcanic eruption in Iceland continues.

The transport ministry said possible closures could continue through Tuesday. The predictions are based on the continuing eruption and current wind and weather conditions.

The Met Office, Britain's weather forecaster, says the wind is expected to change direction Tuesday, which would lower the risks of travel disruptions.

Meanwhile, Italy's civil aviation agency says it has fined Ryanair $3.7 million for failing to help passengers stranded last month when flights were canceled due to the ash cloud. The agency says it found 178 cases of Ryanair passengers who didn't receive mandatory assistance such as food, drink and lodgings.
