Manila hostages may have been killed in "friendly fire"

Investigators in the Philippines say police may have accidentally shot some of the hostages who were killed during a Manila bus hijacking last month.

Eight tourists from Hong Kong were shot dead during a chaotic rescue attempt in which the hijacker was also killed.

The head of the inquiry said there was a strong possibility that at least some of the hostages may have been killed by "friendly fire".
