At least seven of 15 Chinese nationals who were held captive in a tourist bus hijacked by a dismissed policeman Monday are still alive. But four captives were confirmed dead, according to the report filed by ABS-CBN News Channel. The hostage-taker, former Police Senior Inspector Rolando Mendoza, was killed after local police assaulted the bus to save the hostages. Police took injured to nearby hospitals - Philippine General Hospital, Manila Doctors Hospital and Manila Hospital - for treatment.
