Two separate Nigeria suicide bomber detonated themselves in the crowded central market of Jos, northeastern city of Maiduguri, that wounded dozens and killed at least 46 people on Tuesday. It happened in Maiduguri, an Islamic caliphate by Islamist insurgent group known as Boko Haram.

The bloody suicide attacks were apparently done by two bombers who were identified as teenagers. The two women apparently hid their bombs inside their hijabs. They entered the market and detonated themselves one by one.

One Nigeria suicide bomber blew herself up and as people gather to assist the wounded in the blast, another suicide bomber attacked causing commotion as bits and pieces of human parts were scattered on the roads. Victims include marketers, vendors and beggars.

Dozen of wounded victims were treated in Maiduguri University teaching hospital, where some had died. There were also at least 42 casualties that were brought to Maiduguri General Hospital.

Although no one admitted responsibility for the heinous crime of Nigeria suicide bomber attacks, the Islamist insurgent group known as Boko Haram is being suspected for the bomb blast. The group has been ruling the area for five years and is known in using females as suicide bombers.

Boko Haram is concentrated in Maiduguri, the capital of Borno state. The Islamic group had been known to terrorize the Nigerians and had killed at least 1, 500 people in this year alone. Earlier in June, the group has used female Nigeria suicide bomber in series of attacks.

The latest suicide bomber attack was in Nov. 12 where a Nigeria suicide bomber detonated herself up in Nigeria's central Niger state college that killed at least one.

This year, Boko Haram has been active in recruiting males who can explode themselves and lately, they had also recruited numbers of teenage Nigeria suicide bomber. Aside from the human explosives, the group is also using car bombs to expand their terrorist attacks.

In April, the group made international headlines when they abducted over 200 female students from Chibok, about more than 100 kilometers from Maiduguri. Authorities are still looking on the possibility if the students are being used as Nigeria suicide bomber for their attacks.

Negotiations to release the girls were requested from the Islamic group, but it was scraped off following series of territorial suicide bombings as they capture other towns and cities.

Boko Haram main aim in 2002 was to oppose Western education. Boko Haram in the Hausa language means ""Western education is forbidden." However, their goal was changed in 2009 when they started forming Islamic State.

It was also Boko haram that is suspected for the Nigeria suicide bomber attack in June done by five females. At present, Boko Haram is following the ISIS in creating Islamic caliphate, according to BBC.
