Hamas has banned outdoor prayer gatherings in the Gaza Strip, just days after supporters of the rival Fatah group used them to mount mass protests.
About 20 people were injured on Friday when Hamas security forces broke up the biggest show of opposition to the group since it took control of Gaza in June.
The thousands of protesters accused the Islamists of violating civil liberties and using mosques to spread propaganda.
Earlier, dozens of women defied a ban and staged a peaceful protest in Gaza.
The Fatah supporters called for an end to the arbitrary arrests and the alleged beatings of their family members by Hamas.
The Islamist group has insisted it conducts its arrests for reasons of law and order.
