UNITED NATIONS (Sputnik) — Earlier in the day, US President Barack Obama confirmed Mansour's death in a US drone strike carried out several days ago near the Afghan-Pakistani border.
"We obviously have no confirmation… I have no information on that," Dujarric told reporters commenting on that issue.
Mansour has been Taliban's top commander since the death confirmation of the group's longtime leader Mullah Mohammad Omar in July 2015.
Afghanistan is experiencing significant political, social and security-related instability, as radical extremist organizations, including the Taliban, continue to stage attacks against civilian and state targets.
