India on Tuesday hit back at Pakistan over its remarks on New Delhi's engagement with Afghanistan, saying the comments reflected Islamabad's "insecurity and frustration" over the growing ties between the two countries."The comments made by the spokesperson of Pakistan reflect the Pakistani state's insecurity and frustration over the positive trajectory of India-Afghanistan ties," Ministry of External Affairs (MEA) spokesperson Randhir Jaiswal said at a media briefing.The remarks came amid Pakistan's criticism of India's outreach to Afghanistan, with New Delhi asserting that its engagement with Kabul continues to move in a positive direction.On the upcoming BRICS summit, Jaiswal said India was making the necessary preparations and had extended invitations to participating countries."We are making preparations and have extended invitations. We will provide updates on developments in this regard," he said.Responding to a question on the Indus Waters Treaty, Jaiswal reiterated India's position that the agreement would remain suspended until Pakistan takes credible action against cross-border terrorism."The treaty is in abeyance and will remain so until Pakistan irrevocably and credibly abjures its support for cross-border terrorism," he said.
