Nigeria-based militant group Boko Haram has claimed responsibility for a suicide blast that occurred on Friday, killing at least 21 people near the village of Dakozoye, south of Kano, in Nigeria.
The attack on a Shiite Muslim procession took place as they were walking to the city of Zaria to pay homage to the founder of the country.
"It was in a bush area, on a farmland along the highway, our concern is to make everywhere safe. The bomb was made of high calibre explosive," Police Commissioner Muhammad Musa Katsina said on Friday regarding the attack.
According to the SITE Intelligence monitoring service, Boko Haram rarely claims responsibility for the violent attacks.
A week earlier, there was another attack, when two female suicide bombers blew themselves up at a mobile phone market in Kano, leaving 14 people dead and more than 100 wounded.
Since the beginning of this year, Boko Haram has intensified its attacks in Nigeria as well as cross border attacks in Niger, Chad and Cameroon. The countries have formed a multinational joint task force to defeat the group.
According to a report on global terrorism from the Independent Institute for Economics and Peace, Boko Haram was the deadliest militant group in the world in 2014.
