At least 28 people have been killed in three explosions in Brussels, Belgium, Belgian media report.
Ten were killed at a subway station, according to two Belgian broadcasters, and at least 13 were killed at the Zaventem airport, according to public broadcaster VRT.
The terror threat level in Belgium has been raised to four, its highest possible level. There were three explosions in Brussels on Tuesday – one at a subway station and two at the airport and raising the threat level to four means authorities have the ability to deploy the army onto the streets to meet security needs.
Another blast at a subway station occurred in the suburb of Maalbeek, near the European quarter, where much of the European Union is based, according to CNN affiliate RTL. All metro stations in the city have been closed, according to the official Twitter account for the city’s transportation agency.
