KABUL, Afghanistan — A double bombing by the Taliban near the Afghan Parliament office compound in Kabul on Tuesday killed dozens of people during the early-evening rush hour, officials said.

The assault in the Afghan capital was the deadliest of several high-profile attacks on Tuesday, including an explosion at a government guesthouse in the southern province of Kandahar that wounded the provincial governor and the visiting ambassador of the United Arab Emirates.

Wahidullah Majrooh, a spokesman for the Afghan Health Ministry, said 80 injured people and 30 bodies were taken to Kabul hospitals. Many officials feared that the number of casualties would rise.

The Taliban issued a statement claiming responsibility for the Parliament bombings.

One witness who was inside the compound said the attack started when a suicide bomber detonated explosives nearby. Then, as security forces gathered in the area a few minutes later, a car bomb detonated on the busy road that passes in front of the compound, the witness said. He spoke on the condition of anonymity because he was not authorized to talk to reporters.
