Afghan police say six children and one man were killed when a bomb hidden inside a garbage can exploded in southern Afghanistan on Friday.
Police say four children were also wounded by the explosion in Tarin Kowt, the capital of Uruzgan province. It is unclear who the bomb was targeting.
Elsewhere in the south, NATO says bomb attacks killed five service members on Friday.
The international coalition said a roadside bomb killed four soldiers, while a fifth service member died in a separate blast. NATO did not give any other details.
Friday's casualties bring the number of international troops killed in Afghanistan since the start of the year to nine.
At least 544 soldiers died in in 2011, making it NATO's second deadliest year in the 10-year war.
The international coalition is in the second phase of handing security-control over to Afghanistan's army and police in a gradual process due to be completed by the end of 2014.
