Ireland is to donate an additional €1m in funding for emergency food relief and assistance to refugees in the Horn of Africa.

The latest funding brings to €5.6m the total Irish support since the start of 2011 for victims of the humanitarian crisis in the Horn of Africa.

€750,000 will fund the World Food Programme's efforts across the region to dramatically increase the distribution of highly-nutritious foodstuffs to small children and pregnant women, who are particularly vulnerable.

The remaining €250,000 is being provided to the United Nations High Commissioner for Refugees (UNHCR) to support the agency in providing shelter, healthcare, water and sanitation to refugees.

The UNHCR has reported that numbers at Dadaab Refugee Camp in Kenya have swollen to more than 400,000, over four times its intended capacity.
