Afghan presidential candidate Abdullah Abdullah, who pulled out of the race alleging vote-rigging, indicated he might return after a senior election official resigned Monday.
Abdullah, one of two candidates through to a second-round vote on June 14, had accused Independent Election Commission (IEC) Secretariat head Zia-ul-Haq Amarkhil of fraud during the ballot count.
Amarkhil denied that but resigned a day after Abdullah's party aired what it said were intercepted phone conversations in which he ordered officials to stuff ballot boxes.
