A man with a knife at Amsterdam's Schiphol Airport was shot by police Friday, detained, and removed from the scene.

In a tweet, the Marechaussee police service said the "situation is safe."

Schiphol, just outside Amsterdam, is one of Europe's busiest airports.

An airport spokeswoman says the airport's main plaza was and remains evacuated after military police shot the man who threatened to use a knife. Roos van der Ven says Schiphol Plaza, which houses stores, bars and restaurants, was evacuated, but not the parts of the airport behind the check-in area and security checks.

It was not immediately clear what effect the security situation was having on flight departures and arrivals.
