(CNN) President Donald Trump and his national security team are scheduled to meet next week to discuss US strategy for Afghanistan, Pakistan and India, according to two administration officials familiar with the latest thinking. While the meetings could be delayed or rescheduled, the officials told CNN that the ongoing review appears to be drawing to a close. On Friday the Pentagon announced that the US killed Abu Sayed, the leader of ISIS-Khorasan, the terror group's Afghanistan affiliate in a drone strike on Tuesday. But there are major challenges ahead, and Defense Secretary James Mattis has been framing the internal discussions inside the administration as a "South Asia strategy." It encompasses a way ahead in Afghanistan, including the possibility of sending more troops, but also a look at new ideas for dealing with Pakistan, which the US believes is supporting or turning a blind eye to a number of terror groups operating inside the country.
