In Sri Lanka, more than 35,000 civilians have fled the last area controlled by the Tamil Tigers as the Sri Lankan military intensifies its assault on the separatist group. The United Nations says up to 100,000 civilians are trapped in the sliver of coastal jungle controlled by the Tamil Tigers and are living in “dire humanitarian conditions.” Channel 4 in Britain and Al Jazeera have aired some footage from the area that has been closed off to journalists. The video, which was shot by an aid group, showed scores of civilian victims killed last week in fighting. An estimated 4,500 civilians have been killed in Sri Lanka in the last three months.
