Calm has been restored at Safi detention centre where two groups of migrants earlier this afternoon set fire to two sentry boxes and mattresses.
Sources explained that the revolt was caused after a group of migrants was released and another group of migrants, due to be released next week, protested and demanded they be let out today as well.
At one time two separate groups of 12 migrants walked out of the compound but stayed within the confines of the barracks.
Stones were thrown out into the street and a taxiway used by aircraft using the Medavia facility.
The situation was calmed down after representatives of the migrants were addressed by Lt Col Brian Gatt, head of the Detention Service.
At one time soldiers in riot gear were seen on site. No one was injured.
