Last Surge Troops Leave Afghanistan
Around 68,000 U.S. personnel still remain
The last of 33,000 extra US soldiers sent to Afghanistan by President Barack Obama more than three years ago have left the country, the Pentagon says.
They were deployed with the aim of pushing back the Taliban and allowing Afghan government forces time to take over the security of their own country.
Some 68,000 US service personnel remain as so-called insider attacks by Afghan soldiers and police increase.
In the latest violence, a bomb killed five members of the same Afghan family.
