China condemns Brussels attacks
China strongly condemned the attacks on Brussels Tuesday, a Foreign Ministry spokesperson said.
China firmly opposes terrorism in all forms, said spokesperson Hua Chunying in a statement, offering deep condolences to the families of the victims.
"The Chinese people stand with the Belgians and the Europeans," she said.
China is willing to enhance cooperation with Belgium and the international community to jointly face the threats and challenges posed by terrorism to safeguard world peace and stability, said Hua.
She said the Chinese Foreign Ministry and the Chinese Embassy in Belgium are closely monitoring the latest developments to see if there were any Chinese nationals among the victims.
According to media reports, at least 34 people were killed in explosions at an airport and at a city metro station in Brussels.
Belgium on high alert after blasts
Bombings at Brussels Airport, subway kill more than 30 in country's 'black moment'
At least 34 people were killed in twin attacks on Brussels International Airport and a rush-hour subway train in the Belgian capital on Tuesday, triggering security alerts across Western Europe.
Officials at China's embassy in Belgium said that there had been no reports so far of Chinese killed or injured in the attacks. The emergency unit of University Hospital Saint-Luc, which is near the airport, said there were no Asians known to be among those sent there for treatment.
The embassy has asked Chinese to exercise caution if they plan to visit Belgium.
Belgian public broadcaster VRT put the death toll from the attacks in Brussels at 34, with 20 people killed in the blast on a subway train and 14 in explosions at the airport.
"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."
Michel canceled his visit to China. He had been scheduled to attend the Boao Forum this week.
"The visit has been canceled due tow hat happened in Brussels," a source told China Daily on Tuesday.
A witness said he heard shouts in Arabic shortly before two explosions struck a packed departure lounge at Brussels Airport. A federal prosecutor said one of the blasts was probably triggered by a suicide bomber.
There was still some uncertainty about the number of casualties.
The blasts at the airport and subway station occurred four days after the arrest in Brussels of Salah Abdeslam, a key suspect in the terror attacks in Paris that killed 130 people in November.
Belgium's security alert was raised to the highest level after the attacks. Police and troops on the streets were on alert for any further attacks.
Michel said he was sending up to 200 extra troops to the capital to join those already deployed.
Video showed devastation in the hall at the airport, with ceiling tiles and glass scattered across the floor. Some passengers emerged from the terminal with blood spattered over their clothes.
Britain, Germany, France and the Netherlands, all wary of spillover from the conflict in Syria, were among states announcing extra security measures.
All public transportation in Brussels was shut down.
Authorities appealed to citizens not to use overloaded telephone networks. Additionally, extra troops were sent into the city, and the Belgian Crisis Center, wary of a further incident, appealed to the population: "Stay where you are."
Li Wei, an expert of anti-terrorism studies at the China Institutes of Contemporary International Relations, said "there is no doubt" that the explosions in Brussels were terrorist attacks.
He said the blasts bear resemblance to terrorist attacks in London in July 2005 and in Madrid in March 2004, with both targeting densely populated public transportation venues.
Li said it was likely that terrorists linked to Abdeslam, the man arrested on Friday, were behind the latest attacks.
The Brussels airport said it had canceled all flights until at least 6 am local time on Wednesday, and the complex had been evacuated and trains to the airport halted.
Hainan Airlines' flight HU492, which was scheduled to take off at 12:20 pm, was delayed, the airline said, without disclosing a new flight schedule.
The carrier's Airbus 330 was parking at the airport as it was closed.
The subway blast hit the train as it left Maelbeek station, close to European Union institutions, heading to the city center.
European governments moved swiftly to beef up security in the wake of the Brussels attacks.
In France, President Francois Hollande ordered an additional 1,600 police and paramilitary officers onto the streets of Paris.
"This is a war against terrorists," Hollande told reporters. "It will be a long war, but we should be calm and determined.
"Today we are with Belgium," he added.
