Pizzeria in Belgian city explodes, leaving more than a dozen people injured, trapped under rubble

A pizzeria in Belgium's most densely populated city exploded on Monday night, leaving over a dozen people injured and trapped under rubble, officials said. 

The pizzeria, located near Antwerp's busy Paardenmarkt square, collapsed after a massive explosion ripped through it around 10 p.m. local time, according to cops.  

Antwerp officials quickly tweeted that the explosion was "not terror" related, but noted that another three nearby buildings were badly damaged in the blast.

A cause for the explosion was not immediately known.

Investigators said 14 people were injured, including five seriously and one critically. 

Some people were still trapped under the rubble late Monday, officials said, calling the situation "extremely dangerous." Firefighters and other emergency responders were working late, trying to free the trapped victims. 

Mayor Bart De Wever praised the rescue workers and called the explosion "terrible." 

"My thoughts are with the victims and their families," De Wever tweeted in Dutch. 

Belgium has been on high alert since a wave of deadly terror attacks swept across Europe in 2016.
