Ukrainians are expressing their condolences to families of the victims of the terror attacks in Brussels by laying flowers outside the Belgian Embassy in Kiev, QHA reports.

“Think about it: terrorists struck at Europe’s very heart. That’s where NATO headquarters and EU Commission are located. We are not talking about a magazine writing stories Islamists don’t like. This time they targeted the city’s center and airport where a lot of people were. This is horrible,” said Alexander, one of the first to honor the victims of the terror attacks.

Two explosions were reported to have occurred at two subway stations outside EU institutions and near a neighborhood where emigrants reside.

The Belgian government has officially recognized the attacks which claimed the lives of 23 people acts of terrorism.

The attacks might have been retaliation for a March 18 arrest of Salakh Abdesalam, a man suspected of masterminding terror attacks in Paris.
