Tomas Niklasson, European Union's (EU) special representative for Afghanistan, said that the killing of Ayman al-Zawahiri in Kabul reinforces previous doubts about Taliban's commitments.
Niklasson wrote on Twitter on Wednesday that the Taliban had reiterated their commitment at the Tashkent conference that Afghanistan would not become a safe haven for terrorists.
He said that the Taliban had said last week that they are in full control of the Afghan territory in order to convince countries to receive aid for Afghanistan.
He asked the group if the Taliban was unaware, unable or unwilling to take action against the al-Qaeda leader. According to reports, the al-Qaeda leader had been staying at a house owned by Sirajuddin Haqqani, the leader of the Haqqani network and the Taliban's interior minister, in Kabul.
