After cursing the US Ambassador David Friedman as a “son of dog,” Palestinian Authority chairman turned his wrath on the Hamas rulers of the Gaza Strip and clamped down new “sanctions” that will redouble the population’s privations. He told a leadership meeting in Ramallah on Monday that he is punishing its Hamas rulers, whom he accused of orchestrating the failed attempt to assassinate Prime Minister Ramy Hamdallah and intelligence chief Majd Freij. DEBKAfile reveals that Abbas has ordered 1) A ban on Gaza’s internal and external trade. 2) The cutoff of money transfers to Gaza banks. 3) New taxes and 4) A freeze on its share of aid funds. The population already suffers dire shortages from the PA’s refusal for some months to cover the enclave’s electricity and other bills.
