Eritrean migrants are seen in their boat as they are about to be rescued by MSF. 
Medecines sans Frontieres, approximately 10-15 nautical miles off the Libyan coast on July 27, 2015. The MSF-hired ship, named "Bourbon Argos" , was patrolling the waters off of Libya when it encountered two wooden boats carrying a total of nearly 700 migrants, according to MSF. The migrants reported that a third boat left Libya with them, but it could not be located by MSF. It was reported to have been rescued the following day by an Irish ship, with casualties.
