NATO says that two of its service members have been killed in an attack in eastern Afghanistan.

Following protocol, it did not confirm their nationalities. A NATO spokeswoman says the attack happened just before 9 a.m. Monday.

A spokesman for Kabul's police chief, Hashmat Stanekzai, says that a bomb attached to a bicycle detonated near a foreign military convoy in the eastern part of the capital Kabul.

He says one Afghan civilian was wounded.

Monday's deaths bring the total for this month of foreign service members killed in Afghanistan to three. The total number killed this year is 63, 46 of them Americans.

Military convoys and foreign compounds in Kabul have been specifically targeted in recent weeks by insurgent groups waging war against the Afghan government.
