Police in Brussels have made six arrests following Tuesday’s twin airport and metro suicide bombings, after a day on which two Belgian government ministers offered to resign amid mounting criticism of the country’s failure to foil the attacks.

With prosecutors releasing more evidence that the attacks were carried out by the same Islamic State network responsible for November’s carnage in Paris and two suspects still believed to be on the run, several police raids were carried out across Brussels on Thursday evening.

The operation involving Swat teams and armoured cars with helicopter support began soon after 9pm, the state broadcaster, RTBF, said, citing police sources as saying it targeted “people suspected of taking part in the attacks” that killed at least 31 people and injured 300.

Prosecutors confirmed six unidentified people were arrested, including three in a car.
