Thousands of new troops from the United States will soon be joining British, Canadian and Dutch forces in an attempt to reverse gains by the Taliban and expand governance and security.

Nine Afghan policemen were also killed along with a district police chief in a clash the same day with the Taliban in the northern province of Jawzjan.

The deadliest fighting occurred on Thursday, when Afghan and US-led troops killed 30 fighters in the southern province of Helmand, the district where a leading anti-Taliban MP was killed in a bomb attack the same day.

Southern Afghanistan is the centre of the Taliban-led insurgency.
