Hamas's internal security and counter-intelligence apparatus in Gaza includes a specialized unit known as the Radaa Force. It is focused on monitoring threats to Hamas from rival factions, and in identifying dissidents, suspected informants and “collaborators” working with Israel.
The size, command structure, and
exact responsibilities of the Radaa Force are uncertain; Hamas has revealed few
details about it. Its name derives from an Arabic root meaning “deterrence” or
“prevention”.
On August 6 Radaa issued an appeal to the Gazan public in general, and
to members of anti-Hamas militia groups in particular, urging them to
assassinate the leaders of those bodies.
“We say to all members of the
collaborator gangs,” ran the Radaa Force statement, “that assassinating senior
collaborators in these groups will be your salvation – before us, and before
your people.”
What are these anti-Hamas militia
groups, and who are their leaders?
The most internationally visible, and arguably most consequential, of the anti-Hamas armed network in Gaza is known as the “Popular Forces”. Originally led by Yasser Abu Shabab until his death in December 2025, it is now under the leadership of Ghassan Duhine, his deputy. It is the only anti-Hamas force that appears to have reached battalion-scale strength. Estimates in open sources range up to 700 fighters.
The Popular Forces emerged in
southern Gaza, especially around Rafah. On
June 5, 2025, in a video statement responding to allegations by former defense
minister Avigdor Lieberman, prime minister Benjamin Netanyahu acknowledged that
Israel had "activated" and supported clans in Gaza opposed to Hamas.
Subsequent reporting by the Associated Press and other outlets identified Abu
Shabab's Popular Forces as one of the groups receiving such support.
Reported assistance included
weapons, intelligence, logistical support, access to Israeli-controlled areas,
and protection from Hamas. The reported
activities of the Popular Forces include an attack on a Hamas facility near
Khan Younis that the group alleged was being used to store aid confiscated by
Hamas. They also participate in
intelligence gathering against Hamas, securing aid convoys and routes near
Israeli-controlled areas, and protecting access routes to aid distribution
points.
Unlike Fatah, the Popular Forces
do not prioritize Palestinian nationalism or a state-building ideology. Abu Shabab publicly condemned the brutal
onslaught on October 7, 2023 and argued Hamas had brought catastrophe on Gaza.
Politically, this group is the
least clearly ideological of the major formations. Its motivations seem to
combine anti-Hamas hostility, tribal autonomy, economic interests, personal
power, and dependence upon Israeli patronage. Its principal political proposition
is effectively that Hamas must be removed and that local Palestinian actors
should assume control.
The Popular Forces’ politics are moved
partly by clan interests. The Abu Shabab
clan is a large family network in the Rafah area of southern Gaza, connected to
the larger transborder Tarabin tribal network, which extends into Sinai. Its priorities
are protecting its local influence, its territory, economic resources, and clan
autonomy.
Hamas has traditionally sought to
subordinate armed groups and local power brokers to its own authority. During periods when Hamas's control has
weakened because of war, some clans – the Popular Forces among them – have
sought to expand their own security and political roles.
The second particularly important anti-Hamas organization in Gaza is the Counter-Terrorism Strike Force (CTSF), centered on Khan Younis and commanded by Hussam al-Astal. Al-Astal has a security service background within the Palestinian Authority, and his opposition to Hamas is more political and institutional than purely tribal.
The declared objective of the CTSF
(sometimes known simply as the Anti-Terror Force), is the removal of Hamas and
the establishment of an alternative security authority. Al-Astal portrays his organization as an
independent Palestinian anti-Hamas force, though there is significant evidence
of operational cooperation with Israel.
The group crossed an important
threshold on January 12, 2026, when gunmen killed Mahmoud al-Astal, a senior
Hamas police officer. Hussam al-Astal's
organization publicly claimed responsibility. Hamas described the perpetrators as Israeli
collaborators.
The common surname is almost
certainly not accidental. Mahmoud al-Astal and Hussam al-Astal appear to have
belonged to the same extended al-Astal clan, but they were aligned with
opposing political-military camps. Publicly
available sources do not identify their precise familial relationship.
The Hellis clan represents a third
category of anti-Hamas groupings.
The Hellis family, long associated
with Fatah, has opposed Hamas's rule ever since the terrorist organization seized
control of Gaza in 2007. Its most important
contemporary figure is Rami Hellis, who has reportedly formed an armed network
with Ahmed Jundeya, another prominent local figure from Shejaiya, a large
neighborhood in the eastern part of
Gaza City.
Their forces have operated in
areas under Israeli control, and have resisted Hamas attempts to re-establish
its authority in the area. Reuters
describes the Hellis/Jundeya network as one of the principal armed challenges
to Hamas following the 2025 ceasefire.
The al-Majayda clan is based
around Khan Younis and it, too, has become involved in the struggle over
postwar authority. Members have clashed
with Hamas during attempts by Hamas security forces to arrest suspects. Although the clan has criticized Hamas's use
of extrajudicial violence, its political position is notably ambiguous. At
least one senior al-Majayda figure subsequently expressed support for Hamas's
efforts to restore order.
The al-Majayda clan has been
linked to the CTSF through local alliances and cooperation, although the clan
and the militia are distinct entities.
The Doghmosh clan is somewhat
different from the others. It is not primarily an Israeli-backed militia. It is
one of Gaza's longstanding armed families and has historically shifted between
relationships with Hamas, Fatah, Salafist groups, and independent activity.
Back in October 2025 armed members
of the clan fought Hamas forces in Gaza City and it was described as a significant armed rival to
Hamas. Currently there does not seem to be a formal Doghmosh militia.
As for the 20-point Trump peace
plan for Gaza, there is no evidence that any major anti-Hamas militia has
formally adopted the plan as its platform.
Some – especially the Popular Forces – have objectives that do overlap
with key parts of the plan, particularly supporting a post-Hamas administration
after ending Hamas rule. Others –
anti-Hamas though they are – seem more intent on pursuing their own more narrow
interests.
