By Fatos Bytyci KOCANI, North Macedonia (Reuters) -Sporadic violence broke out in North Macedonia on Monday as thousands of people demanded justice for 59 people killed in a nightclub blaze and called for an end to the corruption that they say was behind the country's worst disaster in years.

Dozens of people were killed when a fire ripped through an illegal nightclub in North Macedonia's southern city of Kocani, prompting a bribery and corruption investigation that has led to the arrests of several local officials who allegedly allowed the club to remain open, authorities said Sunday.
