Last summer, Amin Abed almost suffered the same fate, following his decision to speak out against Hamas.

Masked militants beat him senseless, broke bones all over his body and damaged his kidneys. Abed survived but had to seek medical treatment abroad.

Now living in Dubai, he's still involved in the protest movement, and believes that Hamas' authority is diminished.

"Hamas' power has begun to fade," he told me.

"It targets activists and civilians, beats and kills them to scare people. But it's not how it was before."

Before the ceasefire collapsed last month, Hamas fighters seemed intent on highly visible displays of power.

But now, with Israel once again attacking relentlessly, the same gunmen have retreated underground and Gaza's civilians have been plunged back into the misery of war.

Some of the more recent protests suggest that civilians, driven to the edge of madness by a year and a half of Israeli bombardment, are losing their fear of Hamas.
