KHARTOUM, April 14 (Xinhua) -- The security situation in the Sudanese capital city of Khartoum remained calm on Wednesday as the polling process in the country's general elections entered its fourth day.

"The security situation is completely calm with no violation or irregularities affecting the process reported so far," Gen. Ahmed Al-Tuhami, Sudanese police official in charge of securing the elections told reporters Wednesday.

"No suits on violence incidents or irregularities regarding the elections have been filed," he added.

Meanwhile, the Sudanese national elections observation group announced that the technical and logistical problems which accompanied the first days of the polling process at a number of polling stations in some states did not affect transparency and freedom of the electoral process.

"The polling has progressed well after tackling the errors which delayed the process," Tariq Mubarak al-Majzoub, spokesman of the observation group, told reporters.

He expected that the decrease in technical errors during the third day of the polling will result in a rise in the voting turnout among youths and women.

Sudan's National Elections Commission (NEC) announced Tuesday that the final results of the polling will be announced on Tuesday, April 20.
