BRUSSELS, March 22-- Belgian Prime Minister Charles Michel has urged Belgians to "be calm and show solidarity" following Tuesday morning's explosions in Brussels.

At a press conference in Brussels, Michel said extra military reinforcements would be on the streets and border controls toughened.

He did not confirm the death toll from the explosions.

According to media reports, at least 26 people were killed and136 injured in the explosions at the airport and on a city subway train.

"The first urgency for us is to treat the victims, evacuating the people to different hospitals," Michel said.

"This is a dark tragedy for our country ... We are faced with a difficult test and we must be united. We will continue to follow the situation minute by minute with the various security services," said Michel.

Belgian federal prosecutor Frederic Van Leeuw said it was likely that one of the two explosions at Brussels airport was a suicide bomber.
