Iran is not the only place that the US has lost a drone. On December 13th a US drone crashed at the international airport in Seychelles.
The drone is one of several that are part of an American military-base in the Seychelles. The US has had a base in the Seychelles since 2009 and the drones are used to surveil both Somalia and the Horn of Africa - the pre-text being to combat piracy. However, they are not used to track or catch the IUUs present in Somali waters, nor are they used to catch the ships that dump toxic waste in the waters off Somalia, waste that comes mainly from European countries and Australia.
It is interesting to note also that just this month, the Seychelles invited China to also open a military base there. Again the pre-text being anti-piracy.
The Horn of Africa continues to be one of the most militarised ocean areas of the world.
