He calls Isis "a disease" and expresses his gratitude that countries like New Zealand were helping Iraq to rid itself of it through training troops and helping it plan.

He was planning a trip to Mosul this week with stacks of literature to distribute to traumatised citizens on what support they can get from the Iraqi Government.
Tahssen sees a continuing role for the Coalition and the United Nations after the recapture of Mosul is completed, not just for helping to clear the area of explosive devices left by Isis, but in getting schools and hospitals running and advice to make the country less reliant on oil.
• Tahssen flew Mig 23 fighter jets but did not see much action in service. He did not take part in the Iran-Iraq war, graduating just before it ended.
In the invasion of Kuwait, the runway at Basra air base was shot up and couldn't be used.
And in the 2003 invasion of Iraq, Saddam ordered most of the Air Force planes to be disassembled and buried including Tahssen's ones at a base near Baghdad where he was deputy squadron leader.
In 2006 he became head of public affairs for the Air Force and in 2013 for the Ministry of Defence.
