"The coward blast claimed six lives including two security personnel and injured 22 others," Xinhua quoted Sediqi as saying hours after the suicide car bombing.
Shortly before the deadly blast, President Hamid Karzai called on the Taliban and other insurgent groups to attend the upcoming Loya Jirga and present their opinion with regard to the controversial Bilateral Security Agreement (BSA) with the US.
"We have invited them to attend the Loya Jirga which is very important for Afghanistan," Karzai told a press conference inside his fortified presidential palace Saturday morning. "They should attend the consultative Jirga and present their opinion no matter if they are in favour of it."
The blast took place near the venue of the Loya Jirga due to be
held next Thursday amid tight security.
Over 20 people were injured in the ghastly blast
Taliban militants fighting the government and NATO-led troops have denounced the consultative Loya Jirga as a trick to pave the way for permanent presence of the US military in the country and asked Afghans to boycott the traditional grand assembly.
Another armed outfit, the Islamic party of Hizb-e-Islami led by Gulbudin Hekmatyar, has rejected participation in the Loya Jirga, noting it would not tolerate foreign forces presence in Afghanistan.
