Kabul: A Taliban suicide attacker killed three people on an Afghan army bus in Kabul on Thursday, the latest deadly strike against vehicles taking government staff to work in the Afghan capital.
On Wednesday, Taliban suicide bombers killed at least seven people in similar attacks on two buses, one day after the new Afghan government signed a deal for US troops to stay in the country.
The Taliban, who strongly opposed the agreement with the US, claimed responsibility for all three blasts.
"I can confirm a suicide attack on a bus carrying Afghan army staff," Dawlat Waziri, deputy spokesman for the ministry of defence, told AFP. "We have three killed and eight wounded.
"The wounded were immediately taken to the hospital, and they are in a stable condition."
A police statement confirmed the death toll and injured.
Taliban spokesman Zabihullah Mujahid said in a text message: "Around 7:00 am, a suicide attacker targeted a bus carrying Afghan security forces, as a result, a number of officers were killed and wounded."
Afghanistan and the United States on Tuesday signed the long-delayed bilateral security agreement (BSA) to allow about 10,000 US troops to stay in the country next year.
The signing took place on newly-inaugurated President Ashraf Ghani`s first day in office and represented a major step towards mending frayed ties between Kabul and Washington.
After the blasts on Wednesday, the Taliban said they were sending "a clear message to the stooge government that signed the slave pact, and we will step up our attacks after this".
