A bomb exploded on Tuesday near minibuses taking Supreme Court staff home in the Afghan capital, Kabul.
Afghan police say the death toll in suicide attack has jumped to 14, according to AP.
Reuters had earlier reported a death toll of eight.
It was the second big attack in the city in two days.
On Monday, seven Taliban insurgents including suicide bombers attacked Kabul's main airport, Reuters said.
According to Reuters, Supreme Court workers were getting on minibuses to go home when the bomber struck.
“A large explosion occurred near the Supreme Court but it’s still not clear if it was a suicide attack or not,” said Najib Nikzad, the Interior Ministry's deputy spokesman, told Reuters.
Women and children were among the casualties, he said.
The bomb was in a car and was triggered as the minibuses left the compound, Nikzad told Reuters.
The Supreme Court is about 200 meters from the entrance to the heavily fortified U.S. embassy.
“We were sitting in a car when suddenly there was an explosion in the car behind me,” Kabul resident Mira Jan, bleeding from a wound in the head, told Reuters.
“After that I don't know what happened.”
