KHARTOUM, April 22 (Xinhua) -- Sudan government has granted the United Nations Children's Fund (UNICEF) a permit to access Sudan's armed conflict areas, according to a report of United Nations Office for the Coordination of Humanitarian Affairs (OCHA) on Saturday.

"The United Nations Children's Fund (UNICEF) has been granted access to a few hard-to-reach areas such as Kurmuk (Blue Nile State), Golo (Central Darfur State) and Belle El Serief (South Darfur State), the latter had not been accessible for over five years," said the report.

According to OCHA, UNICEF has begun working with government authorities, state officials and partners to bring long overdue assistance, including child protection, education, health, nutrition, water and sanitation services to the vulnerable communities in the newly reached areas.

UN and international organizations have been complaining from restrictions preventing their access to the people affected by armed clashes at Sudan's conflict areas.

Sudan government attributes restriction of movement of UN and international organizations at tensed areas to security reasons.
