Two pro Pales-tine activists being held in British prisons have been transferred to hospital after weeks without food, raising concerns among families, medical professionals, and members of parliament about detainee welfare and access to healthcare.

Amu Gib, 30, who is being held on remand at HMP Bronzefield in Surrey, was admitted to hospital on Saturday after reaching 50 days on hunger strike. Kamran Ahmed, 28, detained at Pentonville prison in London, was also hospitalised after refusing food for 42 days. Both began their hunger strikes on November 2, marking the anniversary of the 1917 Balfour Declaration.

Ahmed’s sister, Shahmina Alam, told Al Jazeera on Monday that his condition had significantly worsened in recent days. She said he has been losing up to half a kilogram per day and warned of the risk of organ damage. Ahmed had previously been taken to hospital in late November after collapsing in his cell due to low blood sugar levels, a condition consistent with hypoglycaemia.

According to the prisoner led group Prisoners for Pales-tine, at least six detainees participating in the hunger strike have now required hospital treatment. Another detainee, Qesser Zuhrah, 20, was hospitalised after 50 days without food and a reported loss of 13 percent of her body weight, according to her legal team. Gib was issued a wheelchair on Friday as their health declined. Other detainees continuing the hunger strike include Heba Muraisi, Teuta Hoxha, and Lewie Chiaramello, who has diabetes and is reportedly alternating days without food.

The detainees are among a group awaiting trial in connection with actions targeting sites linked to the Israeli arms manufacturer Elbit Systems and a Royal Air Force base in Oxfordshire. They are suspected of involvement in a June incident at Brize Norton airbase, where military aircraft were sprayed with paint. UK authorities have cited allegations including criminal damage, aggravated burglary, and violent disorder.

Families, lawyers, and MPs have raised concerns about prison healthcare provision and restrictions on family contact. Jessica Dolliver, Gib’s next of kin, said she learned of the hospital transfer shortly before a scheduled prison visit. Former Labour leader and Gib’s MP Jeremy Corbyn has written to the prisons inspectorate, citing inconsistent medical care for hunger strikers. MPs John McDonnell and Barry Gardiner co signed the letter.

More than 100 doctors have also written to NHS England’s health and justice team urging intervention over the detainees’ medical treatment. Justice Secretary David Lammy has declined requests to meet with the prisoners’ legal representatives.
