A delegation of Government officials and Ireland's ambassador to Sudan, Gerry Corr, are in Khartoum for talks following the kidnapping of two aid workers in Darfur.
Part of the delegation is meeting Sudanese authorities as well as officials from other embassies whose citizens have been abducted in the past.
Another group is travelling to Darfur province.
Ireland's ambassador to Uganda is meanwhile meeting foreign ministry officials in the Ugandan capital, Kampala.
Sharon Commins, who is 32 and from Clontarf in Dublin, and her Ugandan colleague, Hilda Kawuki, were abducted last Friday.
GOAL has pulled its remaining staff out of Darfur until the two have been found, but so far there has been no contact with those who carried out the raid.
