A suicide bomber blew himself up at Brussels airport killing several people and a further blast tore through a rush-hour Metro train in the capital shortly afterwards, claiming nearly a dozen lives, according to public broadcaster VRT.
House searches are being carried out and public transport has been shut down in the city after the deadly twin bombings on the capital's airport and a Metro train.
Security alerts have been triggered across Europe and world leaders have pledged support for Belgium.
The Syrian government is the latest to condemn the attacks, saying they're the result of wrong policies on terrorism.
