Aid workers are finding it hard to operate in a nation grappling with poverty and violence.

PARIS, France (CNN) -- The global relief group Medecins Sans Frontiers, or Doctors Without Borders, has suspended its operations in Afghanistan after a deadly attack on its workers.

The decision to pull out temporarily for "security reasons" came after five MSF workers were shot dead in an ambush in the worst attack on the aid community since the fall of the Taliban.

Three aid workers -- a Dutch man, a Belgian woman and a Norwegian man -- and two Afghan men -- a driver and translator -- were killed in an ambush in the northern part of the country on Wednesday.
