KABUL (Reuters) - Four service members from the NATO-led International Security Assistance Force (ISAF) were killed by a roadside bomb in eastern Afghanistan on Saturday, the coalition said, continuing a trend of rising violence in recent weeks.
ISAF gave no other details about the latest incident. Most of the ISAF troops serving in the hotly contested east, near the border with Pakistan, are Americans.
At least 220 foreign troops have been killed in Afghanistan so far in 2011, 57 in May when the Taliban began their "spring offensive."
