Staff from the Palestinian prime minister's office went on strike Wednesday, joining a widespread work stoppage by civil servants demanding overdue salaries from the Hamas-led government. About 30 workers joined dozens of other striking civil servants, holding up banners that said, "We want our salaries, we have a right to feed our children." Although the protesters were supporters of the rival Fatah party, the work stoppage threatened to embarrass Prime Minister Ismail Haniyeh, a top Hamas official. Hamas leaders oppose the strike, claiming it is politically charged and orchestrated by Fatah. Fatah, which ruled Palestinian politics for decades until Hamas overwhelmingly won legislative elections early this year, still dominates labor unions and security forces.
