Attackers blew up two bridges in Madagascar Monday, further isolating the capital, Antananarivo, where self-proclaimed President Marc Ravalomanana has installed a rival government.
Radio Madagascar, run by Ravalomanana supporters, reports one bridge was destroyed at Miandriavazo, another at Antinafotsy. The blasts follow the destruction of another bridge Friday.
The Ravalomanana government blames supporters of President Didier Ratsiraka for the explosions. Ratsiraka loyalists have been blocking roads into Antananarivo for weeks, cutting off vital supplies to the capital.
The stand-off was sparked by a disputed election last December. Mr. Ravalomanana believes he won outright and accuses President Ratsiraka of rigging the results to force a second round of voting.
President Ratsiraka has ruled out meeting his rival until Mr. Ravalomanana dissolves his government and agrees to a second round of balloting
