Israel threatened Monday to impose new sanctions against the West Bank-based Palestinian Authority after a new unity government was sworn in under a deal with Gaza rulers Hamas. A security cabinet meeting called to discuss the new Palestinian government decided "to authorise the prime minister (Benjamin Netanyahu) to impose additional sanctions on the Palestinian Authority," Netanyahu's ****** said, without elaborating. It added that Israel would hold the PA entirely responsible for any attacks on the Jewish state. The long-awaited unity government took the oath before president Mahmud Abbas after a landmark reconciliation deal in April with the Islamist movement Hamas.
