The Al Aqsa Martyrs Brigade \"Ayman Jawda Squads\", the military wing of the Fatah movement, have claimed responsibility over targeting an Israeli observation tower southeast Gaza, using a Russian-made BM rocket. The rocket, fired at sawn, directly hit the tower, the Brigade said in a statement Monday. It added that this comes within the context of their natural right in response to the occupation\'s constant violation towards their brave prisoners.
