ABUJA - Nigeria's president said Thursday that Boko Haram's mass abduction of more than 200 schoolgirls would mark a turning point in the battle against the Islamists, as world powers joined the search to rescue the hostages.
President Goodluck Jonathan's administration has struggled to contain Boko Haram's bloody five-year uprising and experts have questioned whether Nigeria can end the violence without help.
"I believe that the kidnap of these girls will be the beginning of the end of terror in Nigeria," Jonathan told delegates at the World Economic Forum, thanking Britain, China, France and the United States for their offers of help to rescue the hostages.
The four world powers have pledged varying levels of assistance to track down the girls whose April 14 mass abduction from a school in Chibok in northeastern Borno state has sparked global outrage.
Jonathan's comments echoed those of US President Barack Obama earlier in the week.
Obama said the Chibok kidnappings "may be the event that helps to mobilise the entire international community to finally do something against this horrendous organisation".
The abductions have also led to a growing social media campaign with the hashtag #BringBackOurGirls joined by public figures and celebrities.
US actress Angelina Jolie on Thursday blamed a "culture of impunity" for the kidnapping adding that the world had to "make sure this stops happening and that this is not something that people feel they can get away with..." Most of the insurgents' recent attacks have targeted the remote and impoverished northeast, but two car bombings on the outskirts of the capital Abuja in the last month underscored the grave threat the Islamists pose.
Jonathan had hoped that the World Economic Forum would highlight Nigeria's economic progress and its recent emergence as Africa's top economy, but headlines have remained focused on Boko Haram.
Holding the summit in Abuja despite the recent violence amounted to victory over the extremists, the Nigerian leader said.
"If you had refused to come because of fear the terrorist would have jubilated," he told the more than 1,000 delegates from over 70 countries.
In the latest massacre by the Islamists - which was confirmed by Jonathan's office on Thursday three days after news of the attack emerged - hundreds of people were killed in the town of Gamboru Ngala, also in Borno, Boko Haram's historic stronghold.
World joins hostage search
Nigeria has typically resisted security cooperation with the West, which analysts say has hampered efforts against the militants who have killed thousands since 2009.
American officials have acknowledged that the US military had relatively weak ties with Nigeria and unlike many other African states, the government in Abuja has shown little interest in major training programmes.
