The Uzbek authorities have distributed tonnes of aid since the weekend, including tents, plastic sheeting for shelter, blankets and other relief items. The government is providing medical care and meals to the ethnic Uzbek refugees, some 90 per cent of whom are women and children, UNHCR reported.

A UNHCR emergency team arrived in the Andijan area last week and has since been visiting sites where the refugees are staying and doing assessments. "We were impressed by the organization and maintenance. All refugees get hot cooked meals three times per day, they get bottled drinking water and water for washing," said a UNHCR official.

"We talked to people and they said medical attention and health services are available at any time in the camp. Refugees said they are very grateful to the government and the people of Uzbekistan," he added.

The Uzbek authorities say there are more than 50 sites hosting refugees in the border provinces of Andijan, Ferghana and Namangan. Some refugees are staying in schools, while an unknown number have found shelter with host families.

Members of the UNHCR emergency team said many people were struggling to deal with family separations during their flight from southern Kyrgyzstan. One elderly woman said she planned to return to Osh in southern Kyrgyzstan to look for her daughter and new-born grandchild, who were left behind in the rush to escape violence in the town.

Uzbekistan's Deputy Prime Minister Farida Akbarova, touring one site, told UNHCR staff that managing the crisis was a government priority. "We have mobilized civil servants, teachers, doctors, students to work with the refugees," she said.

Several refugees said they were grateful for the help, but they wished to return home once the situation stabilized in Kyrgyzstan. A joint-UN flash appeal aimed at helping the refugees in Uzbekistan is expected to be launched later this week.

UNHCR estimates that there are some 300,000 people displaced inside Kyrgyzstan, including 40,000 with urgent shelter needs. The authorities say some 9,000 people have returned to their homes from Uzbekistan and within Kyrgyzstan. The major concern mentioned by refugees is family tracing.
