ONGOING: Terrorist Attacks Overnight in Belgium Kill At Least 31

Three explosions rocket Brussels, Belgium overnight in another round of terrorist attacks. The first explosion happened at a busy Subway station killing 10 people. Shortly after, another 2 explosions happened at the airport in Brussels killing 13.

The Belgian Office of the King's Prosecutor described the airport blast, at least, as a suicide attack, according to state broadcaster RTBF.

At least one explosion there happened outside the security checkpoints for ticketed passengers and near the airline check-in counters.

The subway station blast happened in the Brussels suburb of Maalbeek, near the European quarter, where much of the European Union is based.

The Brussels airport tweeted that there have been two blasts and said that the entire building is being evacuated. They also said all airport operations have been suspended and asked those nearby to remain calm.

All flights in and out of Brussels have been suspended. Also, all metro transportation has been suspended until further notice.

The city has been placed on terror alert level 4. It's highest level.

Not just a coincidence I'm sure but the incident comes after Salah Abdeslam, a man who authorities say was involved in the Paris terror attacks last year, was arrested in the Brussels suburb of Molenbeek on Friday.
