Defiant Afghan presidential contender Abdullah is claiming victory, despite the results in two rounds of voting giving a lead to his rival, Ashraf Ghani.
Addressing supporters in Kabul, Abdullah repeated that the election has been marred by fraud.
According to the BBC, pro-Abdullah supporters expressed their anger over the preliminary results that showed Ghani taking a substantial lead, and pulled down posters of incumbent President Hamid Karzai, and chanted: "Death to Karzai. Long Live Abdullah!"
It is being reported that the Abdullah camp might decide to take things into their own hands and create a parallel government, a development that the United States has warned against.
Several influential figures - governors, district leaders, mayors, and warlords - have come out in Abdullah's favour, but Afghanistan is a divided country, as Ghani and Abdullah both command a lot of support.
Preliminary results announced on Monday give Ghani 56.44 percent of the votes in the June 14 run-off and Abdullah 43.56 per cent of the vote.
Votes are being re-checked at more than 7,000 polling stations - nearly a third of the total number. The recount could significantly alter the final result, due on July 22.
