The Kenyan court of appeal has ordered the release of seven medical doctors' union officials who had been sentenced to one month in jail. The officials have been set free pending hearing and determination of the appeal. Officials from the Kenya Medical Practitioners Pharmacists and Dentists' Union were jailed on Monday for contempt of court after they refused to call off the public hospital strike - which has entered its third month. Negotiations will resume immediately, with a team from the Law Society of Kenya and the Kenya National Commission on Human Rights to jointly lead the mediation efforts. The 5,000-member doctors' union wants the government to implement a deal agreed in 2013 to raise basic salaries by 150-180 percent and review working conditions.
