Families of 16 executed prisoners in Baluchistan wrote a letter to the Secretary General, Ban Ki Moon asking the UN to open an investigation in to the execution of their children. 
The letter in part reads:
One year has passed since our children have been executed and after extensive research from one court to another, no one has given us any answer to why our children were executed, and for what reason were they hanged on Oct. 26th without informing their families. Today one year after that horrible crime, we ask Mr. Ban Ki Moon and other human rights organizations to follow and investigate this crime.
