A Taliban suicide truck bomb struck at the entrance of a foreign-run compound in Kabul on Tuesday, killing two Afghan guards

A Taliban suicide truck bomb struck at the entrance of a foreign-run compound in Kabul on Tuesday, killing two Afghan guards, highlighting the security challenges facing the country as NATO forces depart.
  
Taliban insurgents claimed responsibility for the early-morning blast, which shook windows across the Afghan capital and sent a plume of smoke into the sky over the east of the city.
  
After the initial explosion, two other militants were shot dead as they tried to storm the compound. "It was a bomb in a small truck at the gate of a foreign base. Initial reports show two guards killed, several wounded," Najib Danish, deputy spokesman for the ministry of interior, told AFP.
  
"The guards were Afghan. Two other attackers tried to enter the base and were killed by guards." Kabul police chief Zahir Zahir said the attackers drove a truck carrying sand and stone up the compound gate, claiming they were delivering construction material.
  
He said one foreign national was wounded, but gave no further details.
  
Vice-president Abdul Rahshid Dostum arrived at the scene shortly after the blast. "This is not a face-to-face war, it is an intelligence war," he told reporters. "We all know they (the Taliban) have influence over some traitors... but we will find them and they will be brought to justice."
  
A spokesman for the Taliban said via a recognised Twitter account that the attack targeted a foreign forces' intelligence base.
