Barzani agreed to the ceasefire and fired the radicals from the party. Following the unexpected death of Arif, whereupon he was replaced by his brother, Abdul Rahman Arif, the Iraqi government launched a last-ditch effort to defeat the Kurds. This campaign failed in May 1966, when Barzani forces thoroughly defeated the Iraqi Army at the Battle of Mount Handrin, near Rawandiz. At this battle, it was said that the Kurds slaughtered an entire brigade. Recognizing the futility of continuing this campaign, Rahamn Arif announced a 12-point peace program in June 1966, which was not implemented due to the overthrow of Rahman Arif in a 1968 coup by the Baath Party.
