Gaza Strip ? Security men for Gaza’s Hamas rulers clubbed and slammed rifle butts into opponents staging a rare protest Monday, seizing the cameras of journalists covering the event and raiding media offices to prevent news footage from getting out.

The Islamic militant group claims it is willing to tolerate dissent, but the crackdown was the latest in a series of moves to squash opposing voices, including breaking up private parties Friday and Monday where people were singing songs of the rival Fatah movement.

After Hamas gunmen in the Gaza Strip routed forces loyal to President Mahmoud Abbas and Fatah in five days of fighting in June, the group declared an amnesty for former Fatah fighters.

Yet when Fatah and allied groups announced plans for Monday’s rally, Hamas banned “all demonstrations and public gatherings” that do not have official permission.

Buses carrying protesters were halted by Hamas guards who beat passengers, driving them away and confiscating Fatah flags. However, about 300 people got past the militia cordon and demonstrated for 20 minutes.
