Parts of Sweden's Stockholm-Skavsta Airport were evacuated on Sunday and departing flights suspended for several hours, after traces of explosive powder were detected on a piece of luggage at the security check, police said.

But later on, police said that no explosive traces had been found and Skavsta airport was reopened.

Skavsta Airport is the fifth largest in the country and serves primarily low-cost and cargo carriers, handling around 2.5 million passengers a year.

Skavsta is about 100 km (60 miles) south of Stockholm.
