Kabul, May 21 (EFE).- At least seven Afghan police officers died Tuesday when a roadside bomb exploded as their vehicle was passing in the western province of Herat, an official said.
The attack occurred Tuesday morning in the Chest district when the police vehicle was en route to the Obe district in the same province, provincial government spokesman Muhaihuddin Nuri told Efe.
The spokesman blamed the Taliban for the attack, although the insurgents have not claimed responsibility for it.
Homemade bombs are, along with suicide attacks, the Taliban's most frequently used methods of striking Afghan and international security forces, although they cause a high number of civilian casualties.
The attack came a day after a suicide bomber killed the head of the provincial council in the northern province of Baghlan, Rasul Mohsini, and 13 other people in the city of Pul-e-Khumri.
The NATO-led International Security Assistance Force in 2011 began a gradual withdrawal from Afghanistan and the phased transfer of responsibility for security to the Afghan army and police.
This process is slated to conclude in 2014, although many members of NATO, especially the United States, are in favor of maintaining military contingents in the South Asian country beyond that date.
