Tributes To The Brussels Terror Attacks Show Countries Coming Together To Support A Nation In Mourning

Early Tuesday morning, a coordinated of deadly blasts struck Brussels — two in the city's main airport, and a third in one of the city's most central subway stations. At least 20 people have been killed in what's thought to have been an act of terrorism, although the death toll has not been confirmed. "We were fearing terrorist attacks, and that has now happened," said Prime Minister Charles Michel in a statement shortly after the attacks. Tributes for the Brussels attack victims began pouring in as soon as news of the devastating attack spread globally.

Many, including some Parisians, compared Brussels' suffering to that of Paris after the November attacks, which left more than 100 people dead in a series of shootings throughout the city, most devastatingly inside the Bataclan. Others are sharing defiant photos of Brussels citizens, pledging to stay strong and not allow terrorism to frighten the city's residents.

Hundreds of flights in and out of Brussels have been canceled, and all kinds of public transportation in the city have been locked down. Residents are being advised to stay in their homes for fear of further attacks. Belgium has raised its threat level to the maximum, and the city is in deep mourning for those it has lost.
