Zimbabwe's main opposition leader said Sunday that he believed that the pomp with which Robert Mugabe was sworn in for a sixth term Sunday belies desperation. In an interview Sunday after Mugabe claimed victory in an election in which he was the only candidate, opposition leader Morgan Tsvangirai said Mugabe's only choice now was negotiations. Mugabe promised talks with the opposition in his inauguration speech. "He is in bad circumstances," Tsvangirai said in an interview at his Harare home. "He has no option but to negotiate." Tsvangirai came to his home for the interview, but is believed to have returned to his haven at the Dutch Embassy afterward. Tsvangirai fled to the embassy after hearing soldiers were headed to his home soon after he announced last week that he would not participate in Friday's presidential runoff.
