QUETTA - The UN has once again appealed for immediate release of John Solecki, UN Refugee Agency (UNHCR) head in Quetta. 'The UN is aware of the message received on Wednesday evening through the media, and we take it seriously. We are grateful for the support of the leaders of Balochistan for the safe release of John, and acknowledge the concerns of the Balochistan community', Maki Shinohara, UN spokesperson said in a statement. The UN is working on appropriate ways to address the concerns, including sharing information with the relevant authorities such as the newly established Federal Ministry of Human Rights, the spokesperson added. Separately, it is noteworthy that the UN signed an agreement earlier this year with the Ministry of Human Rights, in support of strengthening the promotion of human rights throughout Pakistan , the spokesperson said. 'The UN remains extremely concerned about John Solecki's health, which we are told is deteriorating. John has a serious medical condition which may now be endangering his life, a development that would do nothing to help the cause of those keeping him'. 'The UN once again appeals to those having John to contact us, if not directly, then through a trusted intermediary so that the situation can be resolved in a peaceful dialogue'. Solecki is a humanitarian worker, serving Afghan refugees and host communities as well as Pakistanis affected by earthquakes and floods in Balochistan. We appreciate the continued engagement of the people of Pakistan in securing John's safe release, so that UNHCR can continue its humanitarian work.
