Police are investigating whether the two shootings were linked
Immigrants in a southern Italian town have rioted after six Africans were killed in a suspected mafia attack outside a shop.
People smashed windows and threw rocks in Castelvolturno, north-west of the city of Naples.
The six men from Ghana, Liberia and Togo were shot dead late on Thursday.
Police say the attack may be linked to a row between the Casalesi clan of the regional Camorra mafia and immigrants involved in drug-trafficking.
Two other men were injured in the shooting.
Television footage showed men wielding metal bars and forcing traffic to stop on Friday.
In a separate incident in Castelvolturno, a man, believed to be an Italian national, was gunned down near a local games hall.
Police are now investigating if the two shootings were linked.
They say the murders may be connected to drugs-trafficking in the town, where African immigrants have recently begun dealing autonomously, the Italian news agency Ansa says.
The Casalesi clan - one of the most feared groups in the Camorra - is believed to control drug-trafficking and prostitution in the region.
