His Majesty King Abdullah Monday sent a cable of condolences to US president Barack Obama, condoling him over the incident in a training centre, east of Amman, which claimed the lives of two American citizens.

King Abdullah also wished the injured a speedy recovery.

In another cable, His Majesty expressed deep sorrow and heartfelt condolences to South African president, Jacob Zuma, where one South African citizen was killed in the same incident of the training center.

In both cables of condolences, the King strongly condemned such cowardly act, which is rejected by Jordanians from different walks of life, stressing that an investigation by the government is underway.
