Prime Minister Benjamin Netanyahu's office is ensnared in scandal after two close associates were arrested on suspicion of accepting money from Qatar to promote a positive image of the Gulf Arab state in Israel. The investigation, dubbed 'Qatargate,' centers on accusations that the advisers were hired to run a public-relations campaign to improve Qatar's image while it negotiated on behalf of Hamas for a ceasefire in Gaza. The scandal is the latest to rock Netanyahu, who is already facing a long-running corruption trial and has been accused of undermining Israel's state institutions.
