ROUGH CUT (NO REPORTER NARRATION) STORY: U.S. President Barack Obama in Cuba offered his support to Belgium after a series of attacks saying, "We will do whatever is necessary to support our friends and ally Belgium." Thirty-four people were killed in attacks on Brussels airport and a rush-hour metro train in the Belgian capital on Tuesday, according to public broadcaster VRT, triggering security alerts across Europe and bringing some cross-border traffic to a halt. A witness said he heard shouts in Arabic and shots shortly before two blasts struck a packed airport departure lounge at Brussels airport. The federal prosecutor said one of the explosions was probably triggered by a suicide bomber. The blasts occurred four days after the arrest in Brussels of a suspected participant in November militant attacks in Paris that killed 130 people. Belgian police and combat troops on the streets had been on alert for reprisal but the attacks took place in crowded areas where people and bags are not searched. All public transport in Brussels was shut down, as it was in London during 2005 islamist militant attacks there that killed 52. Authorities appealed to citizens not to use overloaded telephone networks, extra troops were sent into the city and the Belgian Crisis Centre, clearly wary of a further incident, appealed to the population: "Stay where you are".
