Drone strikes are killing civilians across eastern DRC.
Markets, guest houses, villages, all hit in M23-controlled territory, with FARDC blamed for the strikes.
Worst single incident: Mushaki market, May 8.
Up to 24 civilians killed, dozens wounded. Shrapnel pulled from children.
March: a drone hit a UNICEF staff house in Goma, killing a French aid worker.
M23 has responded by striking FARDC's main drone base in Kisangani — hundreds of kilometers away.
