"Two suicide blasts rocked near a sub-office of the National Directorate of Security (NDS), the intelligence agency, at 3.45 p.m. The initial information found 25 dead and several others wounded," a police source told Xinhua.
At least 25 people were killed and several others wounded in two suicide blasts near a government office along a busy road in the western part of Kabul on Tuesday.
The Taliban claimed responsibility for the blasts, which officials said happened on a road near the parliament compound and the private American University of Afghanistan in Kabul.
The violence began when a suicide attacker on foot detonated a bomb near the van, Afghan Interior Ministry spokesman Sediq Seddiqi said. The second blast came from a vehicle that exploded when police arrived to help victims, said Ahmad Wali, a Kabul district police chief.
Taliban spokesman Zabiullah Mujahid said the Taliban were targeting members of the Afghanistan's intelligence agency.
The blasts happened in the late afternoon on Darulaman Road, according to the university.
The university was at least indirectly affected by attacks and kidnappings by Taliban-linked insurgents last year.
In August, two teachers -- an American and an Australian -- were abducted near the school. Days later, a rescue attempt by US Special Operations forces from SEAL Team 6 failed when the teachers were not found at the targeted location.
Three weeks after the kidnappings, gunmen wearing suicide vests stormed the campus and killed 12 people, including students, security guards and police.
