NEW DELHI: Representatives of 44 African countries accused the Indian government on Monday of failing to do enough to stop racist attacks on their nationals following a series of brutal assaults targeting Nigerians.

Around a dozen people were injured, some seriously, when a mob angered by the deathof alocalteenager went on the rampage in a satellite city of New Delhi last Monday.

The violence erupted after a group of Nigerian students who were detained in connection with the teen`s death were released without charge, with police saying there was no evidence against them.

The vicious assault was captured on camera and shared widely on social media, triggering concern over a rise in racist violence against Africans in India.

In a statement, the African Heads of Mission said that `no known, sufficient and visible deterring measures were taken` by the Indian government after previous such attacks.

They said the authorities had failed to `sufficiently condemn` either the latest attacks or past incidences of racist violence against Africans.

Independent investigation The diplomats also called for an independent investigation by groups including the United Nations Human Rights Council into the latest violence, calling it `xenophobic andracial`.

Thousands of people from African countries study and work in India, where many face discrimination. They are often accused of involvement in the illegal drug trade.

The issue was thrown into the spotlight last year when a Congolese teacher was bludgeoned to death allegedly by three Indian men after an argument over hiring an auto-rickshaw in Delhi.

In 2013, a Nigerian national was killed by a mob in the tourist state of Goa, with a state minister later calling Nigerians a `cancer`.

A former law minister was also accused in 2014 of harassing African women af ter he led a vigilante mob through an area of the capital, claiming they were prostitutes.

Police have arrested six of the 10 main suspects involved in the latest attack.

India`s foreign ministry condemned the incident as `deplorable` and assured Nigeria that steps were being taken to protect its citizens in the country, as Abuja demanded `diligent prosecution` of the culprits.-AFP
