A senior Hamas security official was captured alive Tuesday in an unusual operation deep inside Gaza City, as Israeli aircraft launched a wave of strikes to protect the force carrying out the raid.
The full story of the operation remains under wraps, including one particularly intriguing question: who was actually on the ground?
Israeli Defense Minister Israel Katz confirmed that a senior Hamas operative had been captured, but provided almost no details about how it happened.
“A short while ago a senior Hamas terrorist was arrested,” Katz said during a visit to Netiv HaAsara.
“This is our policy: we do not wait for threats, but pursue Hamas terrorists, thwart them and destroy their terror infrastructure.”
Multiple Israeli reports citing security officials said the captured man is the head of Hamas’s General Security apparatus, one of the organization’s most sensitive intelligence and internal security bodies.
He has been widely identified in Israeli reporting as Muin al Arabid, although neither the IDF nor Shin Bet has officially confirmed his name.
Hamas’s counterintelligence apparatus
If the Israeli identification of the detainee is correct, the significance of taking him alive could extend well beyond removing another senior Hamas figure.
Hamas’s General Security apparatus is responsible for counterintelligence, protecting senior Hamas officials, identifying suspected Israeli collaborators and suppressing opposition to Hamas rule.
The IDF has previously said the organization also produces intelligence assessments for senior Hamas officials and helps protect communications and movements between members of the leadership.
Ynet reported that the captured official was responsible for counterintelligence and intelligence inside Hamas.
Other Israeli reports said he could possess extensive knowledge of the security arrangements surrounding senior Hamas officials and Hamas’s internal intelligence mechanisms.
That may explain one of the most striking aspects of Tuesday’s operation.
Israel has repeatedly killed senior members of this same Hamas security apparatus in airstrikes. This time, the apparent objective was to bring the target out alive.
A firefight followed by intense airstrikes
The operation unfolded Tuesday morning in the al Katiba area of western Gaza City.
According to multiple Israeli and Palestinian accounts, the ground force was exposed and came under fire, triggering a firefight with Hamas operatives.
Israeli aircraft then began striking targets around the area.
The IDF issued an unusually brief statement saying it had struck “several targets in the Gaza Strip in order to remove threats to the security forces.”
It added that no Israeli troops were wounded.
Witness accounts cited by Reuters and other media described roughly a dozen strikes in the area, while some Palestinian reports put the number higher.
The director of Gaza City’s Shifa Hospital said two children and a woman were killed and eight people were wounded in the strikes.
Israeli reports said the captured Hamas official was wounded during the fighting. Channel 13 reported that he was moderately wounded and subsequently taken to a hospital in Israel, although that detail has not been officially confirmed.
Who carried out the raid?
This remains the biggest mystery surrounding the operation.
Several Israeli reports, including Ynet and Channel 14, said the ground force was a Palestinian militia operating in cooperation with Israel.
Channel 14 reported that the militia entered western Gaza City to act against a Hamas target, was exposed and became involved in a firefight before the Israeli Air Force provided cover for its extraction.
Other accounts told a different story.
Hamas officials and Palestinian security sources described the raiders as an Israeli special force. Channel 13 also reported exchanges of fire involving Israeli special forces.
Israel has conspicuously declined to settle the question.
According to reporting cited in the research dossier, the military would not clarify whether the “security forces” mentioned in its statement were Israeli personnel or members of a Palestinian force cooperating with Israel.
Channel 14 later said the full method used in the operation had not been cleared for publication.
There is currently no reliable basis for naming the Palestinian militia reportedly involved, and it has not been established that Israeli soldiers personally entered western Gaza City.
Hamas initially claimed the operation failed
The confusion was even greater during the first hours after the fighting.
Ismail al Thawabta, director general of the Hamas run Gaza government media office, claimed that an Israeli special force had been discovered during its mission and that members of the force had been killed.
Israel said there were no casualties among its forces, and no evidence has emerged supporting the claim that members of the raiding force were killed.
Palestinian sources also initially described the operation as a failure.
Later accounts changed the picture.
A Gaza security source quoted by Al Jazeera acknowledged that an officer from Hamas’s internal security apparatus had been abducted, while disputing Israeli reports that he headed the service.
A senior Hamas figure subsequently told Al Araby that Israel had captured a senior figure in Hamas’s internal security apparatus.
The remaining dispute is therefore less about whether someone was captured and more about exactly who Israel now has.
Israeli security sources describe him as the head of Hamas’s General Security apparatus. Other reporting describes him as a former Gaza City internal security chief. Palestinian security sources have insisted that the man captured was an officer rather than the overall head of the service.
Why taking him alive matters
Israel has captured Hamas and Palestinian Islamic Jihad operatives inside Gaza before, and interrogation of detainees has produced valuable intelligence.
But Tuesday’s operation stands out.
If the Israeli account of the detainee’s position is accurate, Israel did not simply capture another field commander. It potentially gained direct access to someone from the upper reaches of the organization responsible for protecting Hamas from Israeli intelligence.
That could make a living detainee considerably more valuable than another name removed from Hamas’s command structure.
For now, Israel appears determined to keep the most interesting part of the operation secret.
A senior Hamas security figure was taken alive from western Gaza City. A firefight erupted. Israeli aircraft intervened to protect the force on the ground.
Who that force was, and precisely what Israel hopes to learn from the man it brought out, remain the unanswered questions.
