Kerry also dismissed criticism of Belgium’s failure to track IS militants before the attacks as a tendency to “jump to conclusions”, but said there was room for improving anti-terrorism co-operation among EU countries.
“The United States is praying and grieving with you for the loved ones of those cruelly taken from us, including Americans, and for the many who were injured in these despicable attacks”, Kerry said after meetings with Belgian prime minister Charles Michel, foreign minister Didier Reynders and Jean-Claude Juncker, head of the EU executive body in Brussels.
“We will continue to provide any assistance necessary in investigating these heinous acts of terrorism and bringing those responsible to justice. We offered today anything they need and they are already taking us up on [it],” Mr Kerry said.
“We will specifically work with them to help in the co-ordination of the flow of information.” He said EU governments had been working over the past year to better exchange counter-terrorism information.
Belgium has drawn international criticism for security lapses in the run-up to the bombings in Brussels Airport and a metro station.
Kerry took issue with the criticism. “This carping four days later is a little frantic and inappropriate. People are jumping to conclusions, they are looking for things that sometimes just are difficult to analyse in the immediate aftermath.”
He told reporters he did not know whether opportunities had been missed by Belgian authorities in tracking IS militants, but said: “This government has been in place for a year and it has moved very forcefully to deal with terrorism.”
Kerry said the US was working with the Belgian government before the attacks and had a “foreign fighter surge team” in Brussels in February to work on specific counter-terrorism efforts. There were also a number of counter-terrorism initiatives scheduled to take place in Brussels before the attacks, he said.
