Nearly 40 women detained at the Delaney Hall immigration detention facility in New Jersey have joined an ongoing hunger and labor strike, according to advocates who announced the development Thursday.

The women, housed in unit 1 of the privately operated facility, have joined striking men already participating in the protest action. Along with their participation, the women released a list of demands they describe as addressing basic human rights concerns.

The striking women are calling on Immigration and Customs Enforcement to release detainees under 21 years old, those with medical conditions, and mothers. They are also demanding improved living conditions within the facility and faster processing of their immigration cases.

Delaney Hall has faced previous criticism over conditions at the facility. The current strike represents an expansion of protest activity that had previously involved male detainees at the New Jersey location.

The facility is operated by a private contractor under ICE oversight. Immigration detention facilities across the country house individuals awaiting immigration proceedings or deportation.
