Imrali Prison is a high-security facility located on Imrali Island in Turkey. It was established in 1999 and is primarily known for housing political prisoners, including Abdullah Öcalan, the founder of the Kurdistan Workers' Party (PKK). The prison is surrounded by water, making it difficult for outside access and communication. The prison has been criticized by human rights organizations for its strict isolation policies and the treatment of inmates. Reports indicate that prisoners have limited access to visitors and communication with the outside world, raising concerns about their rights and well-being.
