Despite Taliban threats, voting was largely peaceful with long queues in cities across the country as voters cast their ballots at around 6,000 centres under tight security.
The Taliban had rejected the election as a foreign plot and urged their fighters to target polling staff, voters and security forces, but there were no major attacks reported during the day.
The head of the Independent Election Commission (IEC) Ahmad Yusuf Nuristani told AFP turnout was better than expected, without giving figures, but lower in rural districts than cities.
Polling stations started to close at 5:00 pm, though officials said that people already in line would still be allowed to vote.
