premise: And as the UN and aid groups delivered relief to nearly a million people hit by floods, the Islamists warned the world body from neither deploying any Ethiopian planes or sending any Ethiopians to work in Somalia.
  "We cannot endure our enemies using humanitarian assistant to spy, if the UN agencies try to use Ethiopian planes, including helicopters to drop food in the flood-hit areas, we will bring them down," said Sheikh Mukhta Robow, the deputy defence chief for the Islamists.
  "We know that every Ethiopian national is a spy. So, we will not tolerate Ethiopian planes flying over our territories," he added.
  Asked why the Islamists were restricting the UN operations, he said: "They drop food today, and tomorrow they drop bombs after they have carried out surveillance over all areas where we are based."
   What will aerial surveillance allow the Ethiopians to do?
hypothesis: drop bombs
