(VOVworld) – Belgium declared 3 days of national mourning on Tuesday to commemorate victims of this week’s deadly attacks in Brussels. The spokesperson for Belgian Prime Minister Charles Michel said that all state agencies will fly the flag at half-mast until the end of day on Thursday. Belgian authorities said that surveillance cameras captured images of three suspected terrorists in the moments before twin blasts rocked Brussels’ Zaventem Airport killing at least 14 people. The men can be seen pushing baggage carts near the check-in area.
