NEW DELHI – India has cautiously responded to an outreach by the Taliban, re-establishing diplomatic presence in Afghanistan in a limited way two months ago in what was a major policy shift for the country.

But the killing of Al-Qaeda leader Ayman al-Zawahiri in Afghanistan in a US drone strike last month and reports of his possible links to the Haqqani Network – the militant group that is part of the Taliban government – have underscored concerns about the Taliban’s continuing links with terror groups.
