At least 70 people have been killed in a suicide bomb attack during a rehearsal for a military parade in the Yemeni capital, Sanaa, officials say, quoted by BBC. On the other hand, Mediafax, quoting AFP informs that no less than 96 have been killed and 300 wounded.The assailant, who was reportedly wearing army uniform, blew himself up among a group of soldiers at al-Sabin Square, near the presidential palace, BBC further informs.An al-Qaeda source told the BBC one of its members had carried out the attack. It was the deadliest incident in the capital since President Abdrabbuh Mansour Hadi took power in February.“We were in a parade, suddenly there was a huge explosion. Dozens of our men were killed. We tried to help them,” Col Amin al-Alghabati told the Reuters news agency. “The suicide bomber was dressed in a military uniform. He had a belt of explosives underneath,” he added. Most of the casualties were from the Central Security Organisation – a paramilitary force commanded by Yahya Saleh, a nephew of former President Ali Abdullah Saleh.An al-Qaeda statement later sent to BBC Arabic said the group had recruited a soldier for the bombing, and that it was carried out in retaliation for “crimes” committed by the Central Security Organisation.
