One person has been arrested, but police believe there may be other offenders involved in the fatal shootings of at least nine people at two mosques in Christchurch.
Sources say nine people have been confirmed dead following the shootings at the Masjid Al Noor on Deans Ave and the Linwood Masjid on Linwood Ave.
Police Commissioner Mike Bush said police were responding to "a very serious and tragic incident involving an active shooter in central Christchurch".
"One person is in custody, however police believe there may be other offenders.
"This is an evolving incident and we are working to confirm the facts, however we can confirm there have been a number of fatalities."
Ahmad Al-Mahmoud, 37, described the shooter as white-skinned, blond, quite short and wearing a helmet and a bulletproof vest. He and others broke a window in a door to escape from the mosque. Prayers started at 1.30pm and the gunman came in about 10 minutes later, when everyone was on their knees praying, he said.
Cricinfo's Bangladesh correspondent Mohammad Isam posted a video to Twitter of the team rushing through Hagley Park away from the mosque.
Bangladesh are due to play New Zealand at Hagley Oval on Saturday. New Zealand Cricket has been contacted about if the game will still go ahead
