(BBC) Days after the deadly attack on a mosque in Christchurch, New Zealand, a private patrol service was launched in New York to protect Muslim places of worship there. The additional security has proved controversial.
On a Friday afternoon, minutes before the muezzins at Brooklyn mosques give the call to prayer, a group of young Muslims is headed to nearby mosques in what look like New York Police Department (NYPD) squad cars.
The cars, with their red and white emergency lights on, will be parked right outside the mosques and stay put while worshippers go in and offer prayers.
The cars and volunteers represent the Muslim Community Patrol, a self-funded group, launched to provide additional security to neighbourhood mosques and Islamic schools in the area at times when they are most crowded.
