Kabul: NATO says nighttime raids that target suspected insurgents will continue, despite repeated protests by Afghan President Hamid Karzai.

NATO spokesman Brig Gen Carsten Jacobson said on Monday that Afghan Special Forces, however, take part in nearly all night raids and their participation is increasing.

The kill-and-capture raids have become a flashpoint for anger over foreign meddling in Afghanistan and whether detention operations will be run by the Afghans or Americans.

Karzai has demanded that foreign troops stop entering Afghan homes.

Coalition officials counter that the raids remain the safest form of operation to take out insurgent leaders.

Jacobson says they account for less than 1 per cent of civilian casualties, and in 85 per cent of cases no shots are fired.
