This is Hamas Al Qassam Brigades spokesperson Abu Obeida threatening Israel for something or other.
I just love that these people call a press conference but cannot show their faces. Abu Obeida himself seems to favor a red keffiyeh, perhaps to distinguish himself from the other masked people he surrounds himself with.
Hamas even makes poster with quotes from him - still masked!
It is hard to take seriously a group that claims to be so brave when their own spokesman is too scared to reveal his face.
