(CNN) Gunmen in the Afghan capital of Kabul attacked a ceremony attended by opposition leader Abdullah Abdullah on Friday, killing 32 people and injuring another 58.

Women and children were among the dead, Health Ministry spokesperson Waheedullah Mayar said.

Abdullah told CNN he heard gunfire and what he thought sounded like rocket fire, and that he managed to escape unharmed from the ceremony in Kabul's west.

Afghan special forced have killed all three attackers involved in the assault, Interior Ministry spokesman Nasrat Rahimi said, while a source told CNN that the gunmen used a high-rise building nearby to shoot at the crowd.
