Anti-terror raids after deadly Brussels explosions turn up nail bomb, Islamic State flag

BRUSSELS – Belgian federal prosecutors say a house search in the Brussels neighbourhood of Schaerbeek has “led to the discovery of an explosive device containing among other things nails.”

Investigators also found chemical products and an Islamic State flag.

Bombs exploded at the Brussels airport and one of the city’s metro stations Tuesday, killing at least 31 people and wounding dozens, as a European capital was again locked down amid heightened security threats.

ISIS has claimed responsibility for the attacks.

The two airport blasts, at least one of them blamed on a suicide bomber, left behind a chaotic scene of splattered blood in the departure lounge as windows were blown out, ceilings collapsed and travellers streamed out of the smoky building.

About an hour later, another bomb exploded on a rush-hour subway train near the European Union headquarters. Terrified passengers had to evacuate through darkened tunnels to safety.

Belgian Federal Police have released the following surveillance image of a suspect believed to have taken part in the Brussels airport attack:

At least one and possibly two Kalashnikovs were found in the departure lounge at the airport, according to a European security official in contact with Belgian police who spoke on condition of anonymity because he was not authorized to speak about the ongoing investigation.

It was not immediately clear whether the firearms were used in the attacks.

Security tightened across Europe

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.

European security officials have been bracing for a major attack for weeks, and warned that the Islamic State group was actively preparing to strike. Abdeslam’s arrest on Friday heightened those fears, as investigators said many more people were involved in the Nov. 13 attacks that killed 130 people in Paris than originally thought, and that some are still on the loose.

Global Affairs Canada said the Canadian embassy in Brussels is “closely monitoring the situation” and trying to determine if any Canadians have been affected.

“What we feared has happened”

“What we feared has happened,” Belgian Prime Minister Charles Michel told reporters. “In this time of tragedy, this black moment for our country, I appeal to everyone to remain calm but also to show solidarity.”

There was no immediate claim of responsibility for Tuesday’s attacks, and Michel said there was no immediate evidence linking key Paris suspect Salah Abdeslam to them. After his arrest Friday, Abdeslam told authorities he had created a new network and was planning new attacks.

“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.”

“There was blood everywhere”

Belgian media reported that 13 people were killed at the airport, where two explosions splattered blood across the departure lounge and collapsed the ceiling. The explosions hit during the busy morning rush. Smoke was seen billowing out of the terminal.

Anthony Deloos, an airport worker for Swissport, which handles check-in and baggage services, said the first explosion took place near the Swissport counters where customers pay for overweight baggage. He and a colleague said the second blast hit near the Starbucks cafe.

“We heard a big explosion. It’s like when you’re in a party and suddenly your hearing goes out, from like a big noise,” Deloos said, adding that shredded paper floated through the air as a colleague told him to run.

“I jumped into a luggage chute to be safe,” he said.

Tom De Doncker, 21, check-in agent intern, was near the site of the second explosion.

“I saw a soldier pulling away a body,” he said. “It felt like I was hit too” from the concussion of the blast.

Zach Mouzoun, who arrived on a flight from Geneva about 10 minutes before the first blast, told BFM television that the second, louder explosion brought down ceilings and ruptured pipes, mixing water with victims’ blood.

“It was atrocious. The ceilings collapsed,” he said. “There was blood everywhere, injured people, bags everywhere.”

“We were walking in the debris. It was a war scene,” he said.

“It was panic everywhere”

Near the entrance to Brussels’ Maelbeek subway station, not far from the headquarters of the European Union, rescue workers set up a makeshift medical treatment centre in a pub. Dazed and shocked morning commuters streamed from the metro entrances as police tried to set up a security cordon.

Francoise Ledune, a spokeswoman for the Brussels Metro, said on BFM television there appeared to have been just one explosion on the subway in a car that was stopped at Maelbeek. Spokesman Guy Sablon said 15 were killed and 55 injured in that attack.

“People were crying, shouting”

At the airport, passengers fled as quickly as they could.

Amateur video shown on France’s i-Tele television showed passengers including a child running with a backpack dashing out of the terminal in different directions as they tugged luggage. Another image showed a security officer patrolling inside a hall with blown-out paneling and what appeared to be ceiling insulation covering the floor.

Marc Noel, 63, was about to board a Delta flight to Atlanta, to return to his home in Raleigh, North Carolina. A Belgian native, Noel says he was in an airport shop buying automobile magazines when the first explosion occurred 50 yards away.

“People were crying, shouting, children. It was a horrible experience,” he told AP. He said his decision to shop might have saved his life. “I would probably have been in that place when the bomb went off.”

With three runways in the shape of a “Z,” the airport connects Europe’s capital to 226 destinations around the world and handled nearly 23.5 million passengers in 2015.

Passengers were led onto the tarmac and the crisis centre urged people not to come to the airport.

Authorities told people in Brussels to stay where they were, bringing the city to a standstill. Airport security was also tightened in Paris, London and other European cities.

In Paris, France’s top security official said the country was immediately reinforcing security at airports, train stations and metros.
