The US Embassy in Afghanistan warned that extremists groups are planning attacks against a "variety of targets" but are taking particular aim at women.
The warning didn't specify which organizations were plotting the attacks. But it comes as the Taliban and government-appointed negotiators are sitting together for the first time to try to find a peaceful end to decades of relentless war.
The "Taliban don't have any plans to carry out any such attacks," the group's spokesman Zabihullah Mujahed told The Associated Press on Friday.
