New Zealand police said on Wednesday they have stepped up patrols at two mosques ahead of the first anniversary of a shooting that killed 51 worshippers, after a distressing image linked to one of the mosques appeared on social media.A lone gunman used a semi-automatic gun to kill worshippers gathered for Friday prayers at two mosques in the city of Christchurch on March 15 last year in New Zealand's worst peace-time shooting.
The attack prompted the government to tighten gun laws and raised questions about the country's image as a peaceful, law-abiding society.
Police said they had increased patrols around the Al Noor and Linwood mosques, the two places targeted in the attack, and would be maintaining a visible presence in the community.
