Peshawar (Agencies): Representatives from the Taliban met an Afghan government delegation in Saudi Arabia this week to discuss security ahead of next month's parliamentary elections and a limited prisoner release, three Taliban officials said.

The meeting comes less than a month before voters are due to go to the polls on Oct. 20 to elect a new Afghan parliament, a process which has been hampered by fears of attacks on polling stations and campaign rallies.

Ensuring the election passes off smoothly and without violence has been a top priority for the Afghan government and its international partners.

"They requested us to help them conduct peaceful elections," said one of the Taliban leaders.

"The Afghan delegation has agreed with us on the release of prisoners," he said, adding that some prisoners facing minor charges had already been released and officials had divided up others into three categories, depending on their importance, for future release.

Both President Ashraf Ghani's office and the US State Department declined to comment. No comment was available from Zabihullah Mujahid, the Taliban 's main spokesman.

The Taliban , who regard the internationally recognised Afghan government as an illegitimate regime imposed by foreign powers, have generally insisted on negotiating only with the United States but there have been regular unofficial contacts.

Earlier this year, Washington dropped its refusal to talk with the Taliban , saying the United States would be willing to participate in Afghan-led peace talks and US and Taliban delegations met for talks in Doha, Qatar, in July.

The meeting in Saudi Arabia came after plans for another meeting with American officials broke down over US demands for a three-month ceasefire, the Taliban representatives said, speaking on condition of anonymity.

"Some of our senior people were not in the favour of holding talks with the Afghan government as until now we were calling them puppets and refused to meet them," said one senior Taliban leader in Qatar.

"But our proposed meeting with the Americans failed to take place due to certain reasons," he said.

The officials said US demands for a ceasefire was something the leadership could not agree to. As a result, no formal meeting was held although there were informal contacts.

"Our agreement for holding the meeting was only to discuss prisoner exchange and the removal of our people from the UN black list so they can travel," said one senior Taliban leader from the movement's political office in Qatar.
