BRUSSELS (AP) - The Latest on explosions at Brussels airport and metro station (all times local):
Belgian federal prosecutor Frederic Van Leeuw is calling all three explosions in Brussels "terrorist attacks."
Two of the explosions on Tuesday morning hit Brussels' Zavantem airport and the third struck in the city's Maelbeek metro station. Belgian media report that at least 13 are dead, and authorities are saying there are dead at both sites.
Van Leeuw says "one attack was probably done by a suicide bomber."
Belgian Prime Minister Charles Michel says "what we feared has happened" and says authorities are worried there will be more attacks.
Speaking a news conference in Brussels, Michel says "there are many dead, many injured" from the attacks earlier Tuesday at the airport and a subway station. He says border controls have been reinforced.
Michel says "we realize we face a tragic moment. We have to be calm and show solidarity."
Brussels police spokesman Christian De Coninck says there were deaths at the Maelbeek police station near European Union headquarters.
He says: "There are victims, serious injury, people have died. I have no idea yet on the numbers of injured or dead."
France's top security official said the country is reinforcing security at airports, train stations and metros after Tuesday's attacks in Brussels.
Interior Minister Bernard Cazeneuve said France immediately increased its vigilance after the attacks. France has been on highest alert since the Nov. 13 attacks in Paris that left 130 dead.
Anthony Deloos, an employee of services company Swissport, said the first explosion took place near a counter where customers pay for overweight baggage. He and colleague said second blast was near the Starbucks.
"Twenty meters (yards) from us we heard a big explosion," and shredded paper was flying through the air, Deloos said. He first thought a billboard had fallen down, but a colleague told him to run.
"I jumped into a luggage chute to be safe," he said.
In a statement marked "aanslagen" - terror attacks in Dutch - the prosecutor's office in Brussels has warned people to stay inside until the situation is cleared up.
After a few hours of uncertainty on the explosion during morning rush hour, it was the first official indication that indeed, they were expected to be terror attacks.

Dutch Prime Minister Mark Rutte says Belgium has "again been hit by cowardly and murderous attacks. Our hearts go out to the victims and next of kin. The Netherlands stands ready to help and support our southern neighbors in any possible way."
Rutte says that "extra alertness is necessary, also in our country. We will take all necessary precautionary measures." Rutte called a meeting Tuesday of his government's Ministerial Crisis Committee to discuss the attacks.
The Dutch anti-terror authority said the country's threat level was unchanged at "substantial." It said extra security measures would be in place at the country's airports and borders.
British airports are increasing security and Prime Minister David Cameron is convening the government's emergency committee after the explosions at Brussels airport and on the city's subway system.
Cameron said Britain would "do everything we can to help."
Britain's official terrorist threat level stands at "severe," the second-highest level on a five-point scale, meaning an attack is highly likely.
