It isn't so much that 19 people were killed and 35 injured in these attacks. It's where the attacks were carried out.

Suicide bombers armed with guns killed at least 19 people and wounded another 35 when they attacked government buildings in Afghanistan's southern Uruzgan province Thursday, public health officials said.

The attack was the deadliest in the south in nearly six months, and comes shortly after the killing of a string of powerful regional leaders, including a former governor of Uruzgan who was gunned down in his home in Kabul this month.

Up to six suicide bombers stormed the provincial governor's compound and the police chief's compound in Tirin Kot, capital of Uruzgan, said Interior Ministry spokesman Sediq Sediqqi.

Three bombers had detonated their explosives and police were engaged in a gun battle with the remaining attackers, he added.

Uruzgan is a largely rural and mountainous province north of Kandahar, to which it has many cultural and tribal links, and the Taliban have long had a presence there.

Very deliberately, the Taliban is showing the Afghan people that they should not put their trust in the government of Hamid Karzai. The attacks on the compounds of the governor and police chief is a sign that no one is safe - especially if you work for the government. These attacks can sap the will to resist unless a strong response is forthcoming from the Afghan authorities. So far, Karzai has done precious little in the aftermath of the targeted assassinations of his half brother and other allies. We'll see what happens to this challenge to his authority.
