Mozambique’s main opposition leader returned from self-imposed exile on Thursday clutching a bible and saying he still rejects the results of a disputed election last year that has sparked more than two months of protests and a violent crackdown by security forces. While Venancio Mondlane stepped off a plane, security forces fired tear gas at hundreds of his supporters who gathered near the main international airport to welcome him home. Mondlane arrived at Mavalane International Airport in the capital, Maputo, to applause from some airport workers and then kneeled in the arrivals hall with a bible in his left hand.
