Border clashes have erupted again between Pakistan and Afghanistan's Taliban forces, with each side accusing the other of breaking a fragile ceasefire.

Residents fled the Afghan city of Spin Boldak overnight, which lies along the 1,600-mile (2,600 km) border between the two countries.

A medical worker in the nearby city of Kandahar reported that four bodies and several injuries had been seen in local hospitals.

There has been sporadic fighting between the two nations in recent months, with Afghanistan's Taliban government also accusing Pakistan of carrying out unauthorized air strikes.

Both sides have confirmed they exchanged fire, but each blames the other for starting the conflict. Each spokesperson has condemned the other's actions and reaffirmed their commitment to protect their borders and citizens.

Footage showed many Afghans fleeing on foot and in vehicles as the clash intensified. Reports indicated attacks came from both sides, including artillery strikes in civilian areas.

This Sunday’s clashes come less than two months after both nations agreed to a ceasefire, mediated by Qatar and Turkey, which had put a halt to previous violence.

The instability at the border has raised concerns, with the Taliban denying accusations of harboring armed groups responsible for attacks in Pakistan. There have been extensive negotiations aimed at finding a lasting peace, which remain ongoing despite current tensions.
