Brussels subway running under heavy guard

A week after the attacks on Brussels airport and a subway station, underground rail services are mostly running under heavy guard.

The metro trains through the Belgian capital are less frequent and only stop at about half the stations.

The Maelbeek station hit by a suicide bomber in the morning rush hour remains closed.

One stop away, Franz Alderweireldt, 82, told said on Tuesday that he takes the subway every day but said that "I think this is not over."

He said that "when terrorists plan an attack, they will do it no matter what, even if there are dozens or hundreds of soldiers or police on the street."

Debaprasad Kar, an insurance company employee, said he has been working from home for the past week.

He said: "I am still a bit jittery, I am afraid to enter the metro station."

Brussels' mayor is acknowledging shortcomings by authorities ahead of last week's attacks but says he hopes the network behind them is being broken at last.

Yvan Mayeur, who is facing criticism in the Belgian media for his own actions before and after the Brussels suicide bombings, said in Paris on Tuesday, "There are certainly some analyses to be done on the investigation. Were there mistakes? Did we miss anything? Certainly. Otherwise these attacks would not have happened."

Asked whether the Islamic extremist network behind the attacks in Brussels and Paris had been badly damaged, he said, "We do believe that and we hope so."

Mayeur met Tuesday with the Paris mayor to discuss the French capital's responses to the November attacks on a Paris stadium, cafes and a rock concert.
