Police say Landvetter Airport in southwestern Sweden has been partially evacuated due to a suspicious package in the domestic terminal.

The move comes amid stepped-up security due to an unidentified threat directed at the airport earlier Thursday.

Police said the domestic terminal was evacuated in the afternoon as police investigated the suspicious package.

It wasn't immediately clear whether the package had any connection to the threat earlier in the day.

Landvetter is Sweden's second-largest airport, and is located about 20 kilometers (13 miles) from the city of Goteborg.
