Kabul increasingly targeted

Recently, relatively peaceful Kabul has been targeted by a series of suicide attacks and bomb explosions.

At least nine civilians, including an Italian soldier, were killed and 12 others wounded in another suicide attack in Paghman, a small town 25 kilometres west of Kabul on 25. Nov.

Following the attack, another roadside mine explosion killed four civilians in the Char Asiab District of Kabul.

But the Afghan Interior Ministry says it has tightened security in the city and is taking further security measures.
