KABUL, Afghanistan (AP) — Afghan authorities say two men have been charged in connection with a suicide bombing that killed 56 worshippers and wounded more than 160 others last year outside a Shiite shrine in Kabul.

The massive attack on Dec. 6, which left behind a grisly scene of bodies and blood, was Afghanistan’s first major sectarian assault since the fall of the Taliban regime more than a decade ago.

Officials with the Afghan intelligence service and Attorney General Mohammed Ishaq Aloko said Tuesday that they charged two men who confessed to transporting the suicide attacker from Peshawar, a city in northwest Pakistan, to the shrine in Kabul.

Lashkar-e-Jhangvi, a Pakistan-based group that has carried out other attacks against Shiite Muslims, claimed responsibility for the bombing.
