From the front-line a drone is heard above, which a soldier accompanying the crew in south-western Yemen said is usually followed by an attack.
Within about 10 minutes, after the crew had driven away, the loud thuds of strikes followed, senior international investigations correspondent Nawal Al-Maghafi reports.
