British-Israeli Nadav Popplewell was taken captive from Nirim kibbutz by Palestinian group Hamas on October 7.

Hamas’s armed wing, the Qassam Brigades, has said British-Israeli captive Nadav Popplewell died of wounds sustained in an Israeli air strike a month ago.

The group’s announcement on Saturday came just hours after the Palestinian group released an 11-second video showing Popplewell with a bruised eye.

In the video republished on social media and cited by Israeli news outlets, a man is seen wearing a white T-shirt and he introduces himself as 51-year-old Nadav Popplewell from the Nirim kibbutz in southern Israel.

Superimposed text in Arabic and Hebrew reads: “Time is running out. Your government is lying.”

Popplewell was taken captive in Nirim during the Hamas-led attack on October 7, according to Israel’s Ynet news site. His mother was also taken as a captive but later released during the exchange of captives and prisoners by Hamas and Israel last year. Popplewell’s brother was killed in the attack, Ynet reported.

The video posted on Saturday on the Telegram channel of Hamas’s armed wing is the third time in less than a month the group has released footage of captives held in Gaza.

On April 27, Hamas released a video showing two captives alive – Keith Siegel and Omri Miran. Three days earlier it also broadcast another video showing captive Hersh Goldberg-Polin alive.

The videos come amid growing domestic pressure on the Israeli government to secure the release of the remaining captives.

Reporting from Amman, Al Jazeera’s Stefanie Dekker, said this tactic of releasing videos of captives on a Saturday, when protests take place in Tel Aviv, is a way of pressurising the Israeli government.

“This is what’s been a drip-feed if you will from Hamas. Where, by releasing videos, at times showing hostages dead, they are trying to put pressure on the Israeli government,” she said.

“But this hasn’t really changed the policies of [the Israeli] government.”

On Saturday, the Hostages and Missing Families Forum in Israel released a statement calling on the Israeli government to strike a deal with Hamas in order to secure the release of captives.

“Every sign of life received from the hostages held by Hamas is another cry of distress to the Israeli government and its leaders,” the families’ group said in its statement.

“We don’t have a moment to spare! You must strive to implement a deal that will bring them all back today.”

Relatives of the captives also accused Prime Minister Benjamin Netanyahu of not caring about those being held in Gaza and called on Netanyahu to resign.

“There is no victory and can be no victory without the return of the hostages,” a spokesperson said at a press conference in Tel Aviv on Saturday afternoon.

Despite the immense pressure, Netanyahu and his government have so far failed to strike a deal with Hamas.

Some 1,139 people were killed on October 7 when Hamas and allied fighters attacked southern Israel, and 250 captives were also taken to the Gaza Strip. Israeli officials say 128 of them are still being held in the Palestinian territory, including 36 who are dead.

Israel’s seven-month military campaign in Gaza has so far killed at least 34,971 people and wounded 78,641 others.
