Boko Haram kidnapping of girls in Northern Nigeria has been spreading terror all over the world since last month. It's not just Nigeria, but the whole world is in sympathy with the plight of the families of the kidnapped girls by alleged Boko Haram gunmen. Recently, there have been another eight girls added to the 200 Boko Haram kidnapping of girls in Northern Nigeria, reports The Guardian.

The suspected Boko Haram gunmen have again kidnapped girls - this time eight - from a village in Nigeria. This Boko Haram kidnapping of girls in Northern Nigeria incident involving eight girls reportedly came after the Islamist rebels abducted 200 girls from a secondary school last month. According to CNN, the Boko Haram are still holding the girls captive.

Police and residents in Northern Nigeria said that the eight girls are aged between 12 and 15. They are reportedly from a village near one of their strongholds in north-east Nigeria.

Lazarus Musa, a resident of Warabe where the attack happened on Monday night says, "They were many, and all of them carried guns. They came in two vehicles painted in army colour. They started shooting in our village. Many people tried to run behind the mountain but when they heard gunshots, they came back. The Boko Haram men were entering houses, ordering people out of their houses."

According to an unnamed police source, the girls had been taken away on trucks together with looted livestock and food. The Boko Haram kidnapping of girls in Northern Nigeria involving 200 girls happened in a secondary school on April 14.

According to The Guardian, Boko Haram leader Abubakar Shekau threatened to sell the girls "on the market". The group has released a video to the media on Monday with the threat. He reportedly told the media that Allah had ordered him to sell the girls.

This Boko Haram kidnapping of girls in Northern Nigeria and the unsuccessful attempts of the Nigerian military to find the group has drawn international attention. This has added to the threat of an escalating Islamic extremist rebellion that resulted in the deaths of more than 1,500 people so far this year.

Boko Haram means "western education is sinful". The United Nations has already warned the group that there was no statute of limitations if they carried out their leader's threat to sell the girls, reports The Guardian. UN Human Rights Spokesman Rupert Colville has addressed a news briefing in Geneva regarding the Boko Haram kidnapping of girls in Northern Nigeria. He said, "We warn the perpetrators that there is an absolute prohibition against slavery and sexual slavery in international law. These can under certain circumstances constitute crimes against humanity."

He added, "That means anyone responsible can be arrested, charged, prosecuted, and jailed at any time in the future. So just because they think they are safe now, they won't necessarily be in two years, five years or 10 years' time." According to reports, he also supports Nigeria's federal and local authorities' actions on working together to rescue the girls.

There have already been protests in the north-east, Abuja and Lagos, the commercial capital because of the Nigeria military's inability to solve the problem of the Boko Haram kidnapping of girls in Northern Nigeria. CBC reports that more protests are expected on Tuesday in Abuja. This is due to delegates' collection of badges where they will be allowed to enter a hotel where a World Economic Forum meeting on Africa will take place. The Forum is scheduled from Wednesday to Friday.

Boko Haram kidnapping of girls in Northern Nigeria isn't the only act of terrorism the group has done these recent weeks. Last week, a bomb in Abuja reportedly killed 19 people, an event which embarrassed the government before the forum.
