A protest is being held outside the Nigerian Embassy in Dublin today - calling for the safe return of 200 schoolgirls kidnapped in the country.
It comes as a team of American military specialists is preparing to join the search for the girls.
President Obama says authorities in Nigeria have accepted his offer of military and law enforcement assistance.
A terror group against female education says it's planning to sell the students who were abducted three weeks ago.
Jacob Zenn is an African analyst and expert on Boko Haram - the militant group behind the kidnappings.
He says the group's leader is using the girls as a human shield.
