Johannesburg, Sep 2 - Security has been beefed up in this South African city after two vehicles of the Bus Rapid Transit (BRT) service were attacked, BuaNews reported Wednesday.

The BRT services were launched in the city two days ago amid a turf war between taxi operators and the authorities handling the public transport network.

The report said gunmen fired at two BRT buses from a minicab Tuesday evening before escaping. Two people, including a police officer, were wounded in the attack.

Johannesburg administration spokesperson Rehana Moosajee said police have been deployed at all the BRT buses and stations.

'We will do everything in our power to ensure a safe journey for everyone using Rea Vaya (BRT service),' Moosajee said.

Meanwhile, the police have detained six suspects in connection with the incident.
