Nurses and midwives staged a protest outside the Nigerian Embassy in Dublin in support of the 276 schoolgirls who were kidnapped in April.
During the protest members of the International Nurses Section of the Irish Nurses and Midwives Organisation handed in a letter for the ambassador.
The letter is calling on the Nigerian government to take immediate action to secure the release of the girls.
The INMO hopes today's protest will highlight the desperate situation the schoolgirls continue to face.
It also hopes to highlight the plight of another 20 women who were kidnapped on Saturday near Chibok by the same terrorist group.
Boko Haram kidnapped more than 250 girls from a secondary school in Chibok in remote northeastern Nigeria on 14 April.
Earlier this week, the group kidnapped another 20 young mothers in the same area.
They were abducted from the nomadic settlement near Chibok in Borno state.
The kidnappings in and around the village of Garkin Fulani, 8km from Chibok, were the latest in a spate in the area.
The Nigerian military has faced mounting criticism for failing to stop militant attacks in the north-east of the country.
Boko Haram has waged an increasingly bloody insurgency since 2009 in an attempt to create an Islamic state in Nigeria.
Thousands of people have died in their attacks and the subsequent security crackdown.
