Two bodies were recovered by rescuers on Tuesday morning in the port city of Antwerp after an explosion caused severe damage to several apartment buildings, Belgian authorities said.
"Police confirm two more victims found under the rubble, both deceased. The victims have not yet been identified," Antwerp police said on Twitter.
Rescuers worked through the night sifting through rubble after the blast damaged several buildings in the Paardenmarkt area of the city on Monday night, causing at least one of the buildings to collapse.
The explosion sent another 14 people to the hospital, one of whom is in critical condition.
Several people, including a couple and their child, were pulled from the rubble alive after being trapped for several hours.
Police said they are still working on determining the cause of the explosion, but said that the blast is not related to terrorism.
Belgium's French-language broadcaster RTBF reported that the explosion was likely caused by a gas leak, but officials have not yet commented on the cause.
Images from the scene show the facades of several buildings almost completely torn off by the blast.
