Zimbabwe on Sunday inaugurated a president for the second time in nine months as a country recently jubilant over the fall of longtime leader Robert Mugabe is now largely subdued by renewed harassment of the opposition and a bitterly disputed election.

The military-backed President Emmerson Mnangagwa, who again took the oath of office, faces the mammoth task of rebuilding a worsening economy and uniting a nation deeply divided by a vote that many hoped would deliver change.

The 75-year-old Mnangagwa, who took power from his mentor Mugabe with the military's help in November , said "my door is open and my arms are outstretched" to main opposition leader Nelson Chamisa after the Constitutional Court on Friday rejected opposition claims of vote-rigging and upheld the president's narrow July 30 victory.
