Following the shooting down of flight MH17, aviation officials have been meeting in Montreal in Canada to discuss air safety.
They have agreed to set up a task force to look at airspace risks, and to push for laws on the use of anti-aircraft weapons. Thousands of flights travel over volatile regions every day.
Eleven countries have current, ongoing conflicts, including Ukraine, Iraq, South Sudan and Mali.
