KABUL/ISLAMABAD, Nov. 6 (Xinhua) -- A district in southern Afghanistan's Kandahar province was attacked, reported local Tolo News late Thursday, saying Pakistani forces opened fire on Afghan border forces.

According to the media, the firing occurred at around 5 p.m. local time, with both light and heavy weapons used. The report said that a commercial market in Spin Boldak district was hit by mortar shells, forcing residents and traders to flee the area.

Pakistani security sources told Xinhua on Thursday that an exchange of fire took place at the Pakistan-Afghanistan border after some elements from the area under Afghan Taliban control opened unprovoked fire on Pakistani posts.

The sources said Pakistani security forces responded promptly and effectively to the firing in Chaman district in the country's southwest Balochistan province, ensuring the safety of their positions.

"According to Afghan authorities, the attack was carried out by a rogue group not acting under official Taliban command," added the sources.

"Pakistani security forces and the Afghan Taliban started coordination after the incident," said the sources, adding that the situation was swiftly brought under control, preventing any escalation.

The sources confirmed that the ceasefire agreement between both sides remains intact, emphasizing that timely action by local commanders helped contain the situation and restore calm.

The incident took place as delegations from Afghanistan and Pakistan began their third round of talks in Istanbul, Turkey, on the same day.
