The deaths raise Thursday's toll to seven international troops killed in the country.
France's defense ministry says one of its soldiers died in a roadside bomb explosion in eastern Afghanistan. The coalition says the other was killed in an insurgent attack in the south.
Earlier, U.S. military officials said five American troops died in a roadside bombing Thursday in the south.
So far this year, 376 American and other NATO service members have died in the war in Afghanistan.
