Lebanese officials say a suspect in the assassination of former Prime Minister Rafik Hariri has been taken to a Beirut hospital.
Former Lebanese intelligence chief Raymond Azar, who was arrested in August, was moved from his prison cell to a hospital intensive care unit. Officials say he is suffering from a heart problem.
His arrest, along with three other Lebanese generals, was on the recommendation of the United Nations commission investigating Mr. Hariri's killing.
The head of that commission, German prosecutor Detlev Mehlis, had been expected to interview five Syrian officials Tuesday in Vienna. But a U.N. diplomat says they are likely to be questioned next week.
Last month, Mr. Mehlis issued a report implicating top Syrian officials in the February assassination. Syria has repeatedly denied any role, and has pledged to cooperate with the U.N. investigation.
