Ethnic Tamil relatives of local Sri Lankan staff of French aid group Action Contre la Faim (ACF) mourn the killing of 17 tsunami aid workers at their funeral in Trincomalee, about 257 km (160 miles) east of Colombo, August 8, 2006. An investigation by Sri Lanka into the killing of 17 tsunami aid workers was seriously flawed, a group of international lawyers said on Monday, warning the rule of law on the Indian Ocean island was under threat.
