NBC News posted:Updated at 9:25 a.m. ET: KABUL, Afghanistan -- Three U.S. Marines were shot dead by an Afghan worker on a military base in southern Afghanistan, an Afghan official told NBC News, raising to six the number of American service members who died in rogue attacks in the country in 24 hours.
he shooting took place on Friday night in the Garmsir district of Helmand province, not far from where three U.S. Marines were killed by an Afghan gunman earlier in the day, Dawood Ahmadi, spokesman for the Helmand province governor, told NBC News' Atia Abawi on Saturday.
In the earlier incident, an Afghan police commander opened fire on the U.S. service members after inviting them to a meeting to discuss security, according to Reuters. Another service member was injured in that attack.
"Let me clearly say that those two incidents clearly do not reflect the overall situation here in Afghanistan," chief ISAF spokesman Brigadier-General Gunter Katz told journalists on Saturday.
Reuters reported that the Marines killed in the latest attack were shot dead by a base employee who turned his gun on them. Military sources said the man had not been wearing a uniform and it was unclear how he got hold of the weapon.
