Afghan presidential contender Abdullah Abdullah has claimed victory in last month's election, despite results giving a lead to his rival, Ashraf Ghani.  Addressing supporters in the capital, Kabul, Mr Abdullah repeated claims that the election was marred by fraud. US Secretary of State John Kerry had earlier warned against a power grab, amid reports that Mr Abdullah was planning a ‘parallel government’.  The Abdullah camp has decided to take things into their own hands and he appears to have some support.  Several influential figures - governors, district leaders, mayors, and warlords - have come out in his favour. But Afghanistan is a divided country: Mr Ghani and Mr Abdullah both command a lot of support. Preliminary results announced on Monday gave Mr Ghani 56.44% of votes in the 14 June run-off. Mr Abdullah, who fell just short of an outright majority in the first round, had 43.56%.  Both men have alleged fraud in the election. Votes are being re-checked at more than 7,000 polling stations - nearly a third of the total number.  Earlier on Tuesday, Mr Kerry said Afghanistan risked losing security and aid support if anyone tried to ‘take power by extra-legal means’.
