Aviation officials 'trying to close safety gaps'

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.
