GENEVA (AFP) - An estimated 80,000 to 100,000 people were killed in nearly three decades of civil war in Sri Lanka between the government and Tamil Tiger rebels, the United Nations said Wednesday. We estimate that between 80,000 and 100,000 people lost their lives in the conflict over 27 years, said Elisabeth Byrs, a spokeswoman for the UN humanitarian coordination office (OCHA). Up to 80,000 people have left the former fighting zone in the last three days, brings the total who fled in recent months to 280,000, according to the UN refugee agency. The United Nations on Wednesday reiterated calls for access to the combat zone, warning that people still needed to be evacuated from the small coastal strip in the northeast of the country. OCHA said relief agencies including the Red Cross still had no information about ill or injured civilians who may remain there. But they were also dealing with a huge influx of tens of thousands of civilians into overburdened government-run camps just outside the combat zone.
