NATO and British officials in Afghanistan say four U.S. service members and a British soldier died Sunday in separate roadside bomb explosions in the southern part of the country.
A NATO statement Monday announced the deaths of the U.S. service members, but did not give any details about the victims' branch of service or exact location of the blast.
The British Ministry of Defense says its soldier died on foot patrol in Helmand province.
Last year, insurgent violence in Afghanistan reached its highest level of the war, which began in late 2001.
Some information for this report was provided by AP and Reuters.
