Four NATO soldiers, one of them French, were killed in attacks in Afghanistan on Saturday, the military said.
The latest bloodshed comes after a month in which 75 soldiers were killed -- the highest number in a single month since the operation began in 2001.
More than 100,000 international troops are deployed to Afghanistan to help the young army fight a brutal Taliban-led insurgency which is mounting ahead of key presidential elections on August 20.
Seventy-five soldiers were killed last month, most of them in attacks, according to the independent
www.icasualties.org website.
The French soldier was killed and two others wounded when French, US and Afghan troops were attacked while on patrol in Kapisa province northeast of the capital Kabul, the French military said in a statement.
France has about 2,900 soldiers in the NATO-led International Security Assistance Force (ISAF) that operates under a UN mandate.
Three other ISAF soldiers were killed in bomb blasts in the south, the alliance force said in a statement that did not release the nationalities of the troops.
"Three International Security Assistance Force (ISAF) service members were killed today after their patrol was struck by two improvised explosive devices in southern Afghanistan," it said in a statement.
Most of the international soldiers in southern Afghanistan are US, British or Canadian nationals.
Explosions caused by homemade bombs, called improvised explosive devices by the military, cause around 70 percent of the casualties to the foreign soldiers deployed to Afghanistan to fight extremism.
Thousands of mostly US soldiers deployed to Afghanistan earlier this year to help secure Taliban strongholds in the south so that Afghans can vote in the election, the second-ever presidential vote in a turbulent history.
