The political climate in Afghanistan continued to heat up as presidential contender Abdullah Abdullah claimed victory in spite of initial election results that calculated his rival, Ashraf Ghani, in the lead.

On Monday, preliminary results released by the Afghan Independent Election Commission revealed that Ghani is in the lead with 56.4 percent of the vote, while Abdullah has 43.5 percent of the vote.

Nevertheless, on Tuesday, Abdullah addressed thousands of angry supporters stating that election fraud is the reason why Ghani is ahead. He also threatened to declare his own government, but, at the same time, urged his supporters to give him time to negotiate.

"We are proud, we respect the votes of the people, we were the winner," said Abdullah in the Afghan capital of Kabul, reports France 24. "We will not accept a fraudulent result -- not today, not tomorrow, never."

The Afghan politician asked the rowdy crowd to remain calm while he comes to a decision, and rejected the notion of a civil war. Instead, he stressed for a unified country.

"We don't want partition of Afghanistan, we want to preserve national unity and the dignity of Afghanistan," he said. "We don't want civil war, we don't want a crisis. We want stability, national unity, not division."

Although both presidential candidates have made accusations about fraud, Ghani delivered a speech on Tuesday agreeing to an extensive audit of over 7,000 polling places and the review of more than three million ballots. He also called for peace and unity, assuring listeners that talk of a separate government would not come into fruition.

"We are all responsible to the people of Afghanistan," he said, reports the New York Times. "This country is a unified nation and it is enthusiastic about a single government, not a parallel one."

In midst of reports that Abdullah would call for a "parallel government," U.S. Secretary of State John Kerry sent a stern warning saying, "Any action to take power by extra-legal means will cost Afghanistan the financial and security support of the United States and the international community," reports BBC.
