Nigeria has joined the U.S led international coalition against the Islamic State militant group.
US President, Barack Obama, said on Tuesday while leading a special United Nations summit on countering violent extremism.
Obama said, Nigeria, Tunisia and Malaysia are the newest members of the U.S.-led international coalition to defeat ISIS.
More than 60 countries, including Arab nations, are working together and launching military airstrikes in an attempt to wipe out IS, which has taken control of large regions in Iraq and Syria.
Obama noted that defeating the Islamic State will take time, but that the militants ultimately will lose because they have nothing to offer but suffering and death.
