(CNN) -- Six NATO forces in Afghanistan died Monday in various attacks, including a roadside bombing in the eastern part of the country that claimed four lives, according to NATO's International Security Assistance Force.
None of the soldiers' nationalities were released.
One soldier died in the east and one in the south. No other details were provided by NATO.
"Our thoughts are with the families and friends of these fine soldiers," said ISAF spokeswoman Lt. Col. Claudia Foss. "ISAF and its soldiers remain resolved to bring security to Afghanistan and rebuilding this proud nation."
It is the deadliest day for the NATO-led mission since five U.S. soldiers were killed on May 30 when their helicopter crashed in Upper Sangin Valley, apparently due to enemy fire. E-mail to a friend
