"Wednesday 17 May – Typhoons attacked terrorist mortar teams in Syria, whilst Tornados destroyed a tank in north-west Iraq and a Daesh position in Mosul...Two Typhoons assisted the Syrian Democratic Forces on Wednesday 17 May. Their first attack was on a mortar which a coalition surveillance aircraft had spotted north-west of Raqqa. Having eliminated that threat, the Typhoons then headed to the east of the country, where they bombed two buildings near Al Ulwah which were being used by another Daesh mortar team and their spotters. A Tornado flight meanwhile patrolled over Mosul, where they used a Brimstone missile to strike a terrorist position. Another Tornado flight later struck a Daesh tank loaded on the back of a heavy transport vehicle in north west Iraq, hitting it with a Brimstone."
