LONDON, Aug 31 (Reuters) - Three aid workers with British humanitarian group Oxfam have been killed by a roadside bomb in northern Afghanistan, the charity said on Tuesday.
It said in a statement two Afghan staff members and a community volunteer were killed in the remote mountainous region of Badakhshan.
"They died in a roadside bomb attack," an Oxfam spokeswoman said.
Violence in Afghanistan is at its worst since Afghan armed groups helped by U.S.-led forces overthrew the Taliban in 2001.
Earlier in August, gunmen killed 10 medical workers, including eight foreigners, in Afghanistan's remote northeast. The Taliban claimed responsibility for that attack.
Afghan officials were not available for comment on the latest attack.
Oxfam, which has been involved in direct humanitarian assistance in Afghanistan since 1991, said it was reviewing its operations in the country.
"We have temporarily suspended operations in Badakhshan and are reviewing all security measures and protocols," Oxfam said, adding that a staff member and a community volunteer had also been wounded in the attack.
"At present, Oxfam has no plans to discontinue its work in Afghanistan." (Writing by Maria Golovnina; editing by Andrew Roche)
