Afghan election contenders in last-ditch bid to rescue power-sharing deal

KABUL (Reuters) - Afghanistan's rival presidential campaigns were holding last-ditch talks on Wednesday to rescue a deal on a national government after a disputed election raised fears of exacerbating ethnic divisions.

Presidential contender Abdullah Abdullah extended a Tuesday deadline to disengage from the political process to allow international efforts to salvage the U.S-brokered deal under which the two sides also agreed to accept the results of a U.N.-supervised vote audit, his camp said.
