KABUL, Afghanistan — A suicide bomber driving a car packed with explosives targeted the compound of a private military contractor on the eastern outskirts of Kabul on Monday, killing at least one person and injuring at least 15 others, including foreigners, the police said.

In a separate episode, 10 girls were killed in a rural district of eastern Afghanistan on Monday when a roadside bomb exploded while they were collecting firewood, the Afghan police said. The office of the governor of Nangarhar Province said the girls were all between 9 and 11 years old. The Ministry of Education said some were as young as 6.

The Kabul explosion sent a large plume of smoke above the capital on the Jalalabad road, a main thoroughfare leading east out of the city lined with shops, yards and industrial units.

The target was a company called Contrack International, said Gen. Mohammed Dawood Amin, Kabul’s deputy chief of police. Officials said Contrack was a construction maintenance company that provided logistics services for the Afghan Army and police and NATO coalition bases.
