BRUSSELS (HOL) —Explosions, at least one likely caused by a suicide bomber, rocked the Brussels airport and subway system Tuesday, prompting a lockdown of the Belgian capital and heightened security across Europe. At least 28 people were reported dead.

Global Affairs Canada says it has no reports of any Canadian citizens being affected by the explosions.

"I strongly condemn today’s deplorable terrorist attacks in Brussels,” Prime Minister Justin Trudeau tweeted in a statement. "My thoughts are with the victims as we stand with Belgium & the EU.”

Belgium raised its terror alert to the highest level, diverting planes and trains and ordering people to stay where they were. Airports across Europe immediately tightened security.

"We are at war,” French Prime Minister Manuel Valls said after a crisis meeting called by the French president. "We have been subjected for the last few months in Europe to acts of war.”
