Gunmen stormed into a newspaper office in northern Sri Lanka and opened fire, killing two employees and seriously wounding another. Describing Tuesday's attack, the newspaper's editor said: "Some men dressed in black broke into our office and opened fire", killing the editorial manager and a circulation assistant and wounding another employee. "They were looking for three of our reporters but they managed to escape because our office is large," said N Vithyatharan, editor of the Tamil-language Uthayan newspaper based in the northern town of Jaffna, 300km north of Colombo.Uthayan is an independent newspaper, but is considered to have close links to Tamil Tiger rebels fighting for a separate homeland for the country's ethnic Tamil minority.
