Gunmen killed the brother of Syria’s parliament speaker as he drove to work in Damascus on Tuesday, the state-run news agency reported, as the international envoy for Syria warned the country could become another Somalia. Mohammed Osama Laham, brother of Parliament Speaker Jihad Laham, was killed in the Damascus neighbourhood of Midan, the SANA news agency said. It was the latest in a wave of assassinations targeting Syrian officials, army officers and other prominent supporters of President Bashar Assad’s regime. Four of the president’s top security aides were killed in a rebel bombing of state security headquarters in Damascus on July 18.
