Brussels attacks: Belgian flag displayed on world monuments in solidarity with victims

At least 31 people were killed and nearly 200 injured in three terror attacks on Brussels Airport and the Maalbeek Metro station

Some of Europe's most famous monuments have been illuminated with the colours of the Belgian flag as a show of solidarity in the wake of a series of terror attacks in Brussels.

As night fell, the Eiffel Tower in Paris was lit up in the black, yellow and red of the Belgian flag.

Berlin's Brandenburg Gate and the Trevi Fountain in Rome were also illuminated out of respect for the victims of the attack.

The Belgian flag was also raised to half mast over Downing Street.

At least 31 people were killed and nearly 200 injured in three terror attacks on Brussels Airport and the Maalbeek Metro station.

Isis has claimed responsibility for the attacks.

Belgian police released a CCTV image showing three suspects moments before the attacks at Brussels Airport which killed at least 11.

Police issued a wanted notice for one of the suspects, who is believed to have survived the attacks.

Shortly after the attacks at the airport, an explosion at the Maalbeek station killed at least 20.

Images of Tintin, the character created by Belgian cartoonist Herge, have been shared widely on social media and the term #JeSuisBruxelles trended on Twitter for much of the day.
