Dutch counter-terrorism officials said on Tuesday they were boosting security at national airports and tightening controls on the southern border with Belgium amid a series of blasts in Brussels.
"Out of precaution we are taking a number of additional measures in the Netherlands," the Dutch coordinator for terrorism and security said, adding there would be "extra police patrols at Schipol, Rotterdam and Eindhoven and border controls on the southern border".
French President Francois Hollande called an emergency meeting of senior government ministers on Tuesday after a series of explosions in Brussels.
Prime Minister Manuel Valls, Interior Minister Bernard Cazeneuve and Defence Minister Jean-Yves Le Drian were among those present, according to the president's office.
The deadly explosions were carried out at Brussels airport earlier on Tuesday by a suicide bomber, Belgium's federal prosecutor said according to broadcasters VTM and RTBF. A further blast struck a metro station in the capital shortly afterwards.
The blasts at the airport and metro station occurred four days after the arrest in Brussels of a suspected participant in the November militant attacks in Paris that killed 130 people.
Police had been on alert for any reprisal action in both capitals, which lie about 315 kilometres apart across an open border.
British Prime Minister David Cameron, whose country is also on a high security alert, expressed shock over the attack. "We will do everything we can to help."
