The US has announced it will hold peace talks with the Taliban.
For the past 12 years, American troops with other Nato forces have been in Afghanistan fighting against the group.
The Taliban controlled Afghanistan until 2001, when they were overthrown by British and US troops. But fierce fighting continues there even today.
The talks will start within days. But there are conditions: the Taliban must agree to respect the rights of women and minority groups.
They also want the Taliban to break ties with al-Qaeda, an extremist group who've claimed responsibility for terrorist attacks around the world.
The announcement of peace talks was made on the same day that 4 US servicepeople were killed when the Taliban attacked one of their bases in the country.
Today is also the day that Afghanistan's army officially takes over security in the country.
The Afghan government are not happy about the talks and the Afghan President, Hamid Karzai, has said they won't join in the discussions.
They've also suspended planned talks with the US about security issues in Afghanistan.
