Palestinian Prime Minister Ismail Haniyeh warned on Sunday that early elections would lead to chaos, saying his Hamas-led government opposes "political tyranny." Palestinian President Mahmoud Abbas, of Hamas' rival party Fatah, has threatened to call early elections if deadlocked negotiations with Hamas over the formation of a national unity government are not revived. Haniyeh, whose Hamas Islamist group took control of the Palestinian government after an election victory earlier this year, made his comments during a farewell ceremony at the end of his four-day visit to Tehran, according to Iran's state-run news agency, IRNA. "One should not violate the affairs of the Palestinian nation with various plans," IRNA quoted Haniyeh as saying. "Since the beginning of taking office, we have felt that some bodies have been daggering us from the back."
