KHARTOUM (Reuters) - Four hundred Ethiopian refugees from Eritrea reached the Sudanese border town of Kassala on Sunday, the government-owned al-Anbaa newspaper said on Monday. "The latest batch of Ethiopian refugees fled Eritrea because of the recent incidents between Eritrea and Ethiopia," the daily said, referring to the border war between Eritrea and Ethiopia which has driven a large number of refugees into Sudan. Al-Anbaa quoted the refugees as saying they had to leave because of the harsh treatment they had received from the Eritrean authorities. "Some of them said the Eritrean authorities expelled them from their land and beat others to death," the newspaper said, but gave no casualty figures. It said the refugees had asked the Sudanese authorities to repatriate them to Ethiopia. Sudan hosts the second largest number of refugees in Africa after Guinea - which has tens of thousands from neighbouring Sierra Leone and Liberia - according to figures from the United Nations High Commissioner for Refugees (UNHCR) in December. A UNHCR fact sheet said Sudan had 390,000 refugees, well below Khartoum government estimates of more than one million, mostly from Eritrea and Ethiopia.
