As Belgium begins to piece together the unknowns from Tuesday morning's triple bomb blasts in Brussels, cities around the world have been showing their support for the grieving nation.
The attacks, for which ISIS claimed responsibility, killed more than 30 and injured nearly 200.
In Brussels, people are continuing their daily lives, but not without pause for yesterday's events. City squares have been filled with flowers, and roads and buildings are covered with chalk messages of strength and love.
Around the world, people in other countries are showing their support as well.
In Paris, a city which recently has become all too familiar with terror attacks, Mayor Anne Hidalgo tweeted a picture of the Eiffel Tower lit in black, yellow, and red with the message "Paris and Brussels are united."
The Belgian flag was projected on the famous Brandenburg Gate in Berlin and the Trevi Fountain in Rome, and raised on Downing Street in London. Black cab drivers in London put a hold on their planned Wednesday protest against private car services out of respect for the victims in Brussels. In Dubai, the Burj Khalifa was also lit up in black, yellow, and red.

And in the makeshift refugee camps on the Greece-Macedonia border, stranded migrants held up signs in solidarity — a reminder that the attacks in Brussels are an example of the exact kind of terror millions are desperately trying to flee.
