Scores of Nigerians took into the streets to condemn the incarceration of imprisoned Shiite cleric and leader of the Islamic Movement of Nigeria (IMN), Sheikh Ibrahim al-Zakzaky, his wife and hundreds of other Muslims as illegal.

According to the official website of IMN, the protesters staged rallies in the areas of Kaduna, Katsina and Yola, demanding the release of the cleric.

The demonstrators were held in the run-up to the Islamic Unity Week as the Nigerian government moved the cleric and his wife to an unknown place.

The senior Muslim cleric and his wife were detained on December 14, 2015, after deadly conflicts between the supporters of the IMN movement and Nigerian forces.

During the clashes, nearly 350 members of the Shiite movement were killed and the sheikh was injured.

Back in November, Nigerian forces opened fire at a group of Shiite Muslims holding a demonstration in preparation for the upcoming Arbaeen mourning rituals, which mark 40 days after the martyrdom anniversary of Imam Hussein (AS), the third Shiite Imam.

Troops blocked the road and fired live rounds and tear gas to disperse hundreds of people, including women and children, marching in the northern city of Kano on Sunday.

The Islamic Movement in Nigeria (IMN) said that one person was killed and several others were injured during the incident.
