KABUL, Afghanistan (AP) — Taliban militants unleashed car bombs at the U.S. Consulate in western Afghanistan today, triggering a firefight with security forces in an attack that killed at least two Afghans and wounded 17. The U.S. said its personnel from the mission were safe and that most of them were temporarily relocated to Kabul, while American forces secured the site.

The attack in the city of Herat — along with a suicide truck bombing in the country’s east that wounded seven Afghans today — raises concerns of spreading insecurity in Afghanistan as U.S.-led troops reduce their presence ahead of a full withdrawal next year. It came two days after the 12 anniversary of the Sept. 11 attacks, and was a harsh reality check for Afghans who had spent the previous day and a half celebrating their nation’s first international soccer championship.

Taliban spokesman Qari Yousef Ahmadi took responsibility for the Herat attack in a phone call with The Associated Press. Afghan and U.S. officials, meanwhile, offered slightly different accounts of what happened — differences which could not immediately be reconciled.

According to Gen. Rahmatullah Safi, Herat province’s chief of police, the attack began around 6 a.m. when militants in an SUV and a van set off their explosives-laden vehicles while others on foot fired on Afghan security forces guarding the compound in the city, 625 miles from Kabul.

An Afghan police officer and an Afghan security guard were killed, though it was not clear whether they died in the explosions of the two vehicles or in the gunfire, Safi said. At least seven attackers were killed, including the two drivers of the explosives-laden vehicles, he said.

Herat hospital official Sayednaim Alemi said at least 17 people were wounded, and that two dead bodies were brought to the medical center. It was not immediately clear if the dead were victims mentioned by Rafi.

U.S. State Department deputy spokeswoman Marie Harf said in a statement that the assault began around 5:30 a.m., when “a truck carrying attackers drove to the front gate, and attackers — possibly firing rocket propelled grenades and assault rifles — started firing at Afghan forces and security guards on the exterior of the gates. Shortly after, the entire truck exploded, extensively damaging the front gate.”

Rafi said U.S. special forces secured the compound and that no attackers managed to breach it. Harf ’s statement said “American security personnel” were among the responders, and that “it appears American and contract security personnel addressed any attackers who managed to enter the compound.”

Robert Hilton, a spokesman for the U.S. Embassy in Kabul, said that “all consulate personnel are safe and accounted for.” He added that most of the staff have been temporarily relocated to the Afghan capital, but that some essential personnel remain in Herat. He declined to give further details.

Footage broadcast on Afghanistan’s Tolo television network showed Afghan police dragging away a badly bloodied man from the scene. Rubble and twisted pieces of metal lay strewn in a seemingly wide area near the consulate, the footage showed.

Afghan and U.S. officials condemned the attack.

The Afghan Foreign Ministry said it “illustrates both the desperation of the enemies of Afghanistan and their heinous, wanton disregard for the lives of Afghanistan’s peace-loving citizens.”
