GAZA, July 16 (Reuters) - The Gaza Strip's Hamas rulers have been unable to pay salaries for 50,000 public sector workers, with officials in part blaming a delay in a monthly payroll grant from Qatar, a crucial aid donor to the impoverished Palestinian enclave. The salary crisis has sparked an unusual amount of criticism on social media in Gaza, including by some of Hamas' own employees. It currently pays $30 million per month in stipends for families, fuel for electricity, and to help pay public sector wages. Hamas officials say no salary aid has been received since just over half of a $5-million grant to support the May payroll. Public sector employees have not received full salaries since 2013.
