The six US troops killed in Afghanistan on Monday were "outstanding" and "brave" US President Barack Obama said, as he thanked the American military members on Friday during a Christmas Day visit to Marine Corps Base in Kanoehe Bay, Hawaii.
Obama said, "Even though we have been able to reduce the number of folks we're deploying to places like Iraq and Afghanistan, there are still folks over there every single day and it's still dangerous as we saw this past week with the outstanding, brave men and women who were killed".
A suicide bomber with a motorcycle had blew himself up near a joint US-Afghan patrol near Bagram Air Base in Afghanistan on Monday and killed six American soldiers.
Taliban Spokesman Zabidullah Mujahid claimed responsibility for the attack and said that 19 American soldiers were killed.
Bagram is located about 40 km (25 miles) from the north of Kabul and hosts one of the main bases which has 9,800 US troops in Afghanistan after foreign troops finished combat operations last year.
