(CNN) Clashes in Tunisia have continued between protesters and police for a second night as anger grew over the death of a journalist who set himself on fire.

Abderrazek Zorgui posted a video on social media before he died on Monday, saying that he was going to set himself alight due to the difficult social circumstances experienced by him and his family. The video has since been removed.

In a statement, Tunisia's national journalists' union said Zorgui died after he set himself ablaze "due to harsh social circumstances and a lack of hope."

Police fired tear gas at dozens of people who took to the streets Monday night in the city of Kasserine.

The union also condemned "the countries which have contributed to making the field of journalism a hot-bed for corruption" and added that it would be announcing a series of protests in the coming days.

After Zorgui's death, demonstrators clashed with police on the streets of Kasserine in western-central Tunisia.
