A gunman burst into a casino in the Philippines on Friday, firing shots and setting gaming tables alight, and at least 36 people were killed, most suffocating in thick smoke, in what officials believe was a botched robbery, Reuters reported. Most of the dead suffocated in the chaos as guests and staff tried to flee choking smoke at the complex after the attack began shortly after midnight (1600 GMT). Oscar Albayalde, chief of the capital's police office, said those that died were in the casino's main gaming area. "What caused their deaths is the thick smoke," he told reporters. A Resorts World Manila official said the dead included 13 employees and 22 guests.
