Guinea-Bissau: Police fire tear gas at marchers

Police in Guinea-Bissau fired teargas on Tuesday to stop hundreds of supporters of an ousted former ruler, as the interim leader said the country risked sinking into political chaos. Hundreds of supporters gathered outside the house of Kumba Yalla, who was ousted as leader in a bloodless coup in 2003 but says he is still the rightful head of state and declared himself president at the weekend.
