KABUL (Reuters) - A suicide bomber attacked an Afghan army bus on the outskirts of Kabul on Saturday, wounding up to 10 soldiers and civilians, less than a week after a suicide attack on a foreign military base in the city, a police spokesman said.
"A suicide bomber on foot attacked an army bus," said Hashmat Stanekzai, spokesman for Kabul Police Chief. Seven soldiers and three civilians were wounded, he added.
Taliban-led militants have stepped up their fight this year against the Afghan government and its Western backers, at a time when Kabul has announced security responsibilities for seven areas will be handed to Afghan forces within months.
The attack came less than a week after three suicide bombers in burqas targeted a foreign military base in the Afghan capital. They did not kill anyone other than themselves.
The Taliban claimed responsibility for that attack, but could not immediately be reached for comment on the bus bomb.
The bus attack comes after more than a week of protests denouncing the burning of a Koran by a militant, Christian U.S. pastor.
Some turned deadly, in the north when a mob over-ran a U.N. compound and killed at least seven international staff in the worst-ever attack on the United Nations in Afghanistan, and in southern Kandahar at least 12 people died in rioting.
