ROUGH CUT (NO REPORTER NARRATION) STORY: Britain's prime minister on Tuesday condemned a series of attacks in the Belgian capital that left at least 26 people dead. The Belgian health minister said 11 people were killed in twin attacks at Brussels airport and 81 were wounded. A rush-hour metro train was also attacked. The STIB public transport operator said 15 were killed on board the train blast and 55 injured. David Cameron said the Belgium attacks could have occurred anywhere in Europe. "We need to stand together against these appalling terrorists and make sure they can never win," he said. Britain, Germany, France and the Netherlands, all wary of spillover from conflict in Syria, were among states announcing extra security measures on Tuesday. All three main long-distance rail stations in Brussels were closed and train services on the cross-channel tunnel from London to Brussels were suspended. Security services have been on a high state of alert across western Europe for fear of militant attacks backed by Islamic State, which claimed responsibility for the Paris attacks last November.
