Several Taliban militants killed as fighting rocks insurgent bastion

Dozens of Taliban fighters were killed in fierce overnight fighting between Afghan forces and militants who attacked multiple checkpoints in the insurgent bastion of Kandahar.

Taliban militants attacked checkpoints in five districts surrounding the city of Kandahar.

The security forces countered with heavy air and ground assaults, killing 51 terrorists and wounding nine.

Seven members of a family were also killed in an Afghan air strike in one of the districts.

The ministry of defence said it was investigating the incident.  

The fighting lasted for several hours through the night, marked with continuous gun battles and heavy bombardments, an AFP correspondent reported from Kandahar.

The Taliban launched a similar offensive in the neighbouring province of Helmand in September that sent tens of thousands of residents fleeing.

That attack, which also targeted the provincial capital of Lashkar Gah, prompted the US to call in air strikes to defend Afghan forces.

Since a US-Taliban deal in February, the insurgents have not carried out major attacks on key cities but have launched near-daily assaults against Afghan forces in rural areas.

The surge in violence in recent months comes as the Taliban and Afghan government engage in peace talks.

In recent months, Kabul has seen several deadly attacks claimed by the jihadist Islamic State group, including a rocket attack Saturday that killed one civilian. 

On Sunday, a bomb planted on a vehicle killed two civilians in the capital, police said.

The southern province of Kandahar is the birthplace of the hardline Islamist movement, and over the past few weeks militants have launched attacks in districts on the outskirts of the city of Kandahar, the provincial capital.
