International police agency Interpol said Friday that is ready to provide any support needed from its side, to rescue the schoolgirls kidnapped by the Islamist militant group Boko Haram in Nigeria.

Ronald K. Noble, the Secretary General of Interpol, said in a letter written to the Nigerian President Goodluck Jonathan that the police body is ready to provide any assistance needed in locating and bringing more than 200 girls, still with Boko Haram, back home safely. The organization also ordered an immediate publication of Yellow Notices, which would be circulated to 190 member countries to help catch the kidnappers sooner.

"The appalling abduction of the schoolgirls has been compounded by their continued detention at the hands of depraved cowards who understand neither mercy nor compassion," Noble said in a statement released Friday by France-based Interpol, adding: "Our thoughts are with the victims of the kidnapping and their loved ones at this very difficult time, and Interpol stands ready to provide whatever assistance is asked by Nigerian authorities."

The organization has also agreed to send an Incident Response Team to Nigeria to help authorities with “on-ground assistance to the National Central Bureau in Lagos and any involved national law-enforcement agencies requiring investigative and analytical support,” Interpol said in a statement.

Several world powers, including the U.S., the UK, France and China, have agreed to assist the Nigerian government to bring back the girls who were kidnapped by Boko Haram last month from their school dormitory in Chibok. The Nigerian military rescued nearly 100 girls from the group later in April.

But Boko Haram, whose name means “Western education is a sin,” later kidnapped 11 more girls and released a video where the group’s leader, Abubakar Shekau, said that they will “sell” the girls. The group also attacked a marketplace on Gamboru Ngala, earlier this week, which led to nearly 300 people getting killed in the clashes.

At the World Economic Forum in Abuja on Thursday, Jonathan vowed to rescue the girls, though he acknowledged that he did not know where the girls were.

"As a nation we are facing attacks from terrorists," Jonathan said, according to Al Jazeera, adding: "I believe that the kidnap of these girls will be the beginning of the end of terror in Nigeria."
