A powerful bomb exploded outside the gates of Kabul University in the Afghan capital on Friday, killing at least six people and wounding 27, according to police and health officials.
No group immediately claimed responsibility for the attack, the latest to target Kabul. Both the Taliban and the Islamic State group often stage large-scale bombings in the city, targeting Afghan forces, government officials and minority Shiites.
The early morning blast also set two vehicles ablaze although it wasn't clear if the attack was carried out by a suicide bomber or a remotely detonated bomb, said Kabul police spokesman Ferdous Faramarz.
The casualty tolls were released by the Health Ministry spokesman, Dr. Wahidullah Mayar, who tweeted that "6 people have been martyred & 27 more wounded, as a result of today's explosion in Kabul. All the wounded patients were evacuated to our hospitals and have been receiving the required treatment."
