Palestinian President Mahmoud Abbas has accused Hamas of needlessly extending fighting in the Gaza Strip, causing a high death toll.
Abbas told Palestine TV in remarks broadcast Friday that "it was possible for us to avoid all of that, 2,000 martyrs, 10,000 injured, 50,000 houses (damaged or destroyed)."
Israel and Hamas militants fought for 50 days before reaching a truce on Tuesday.
More than 2,100 Palestinians were killed, including hundreds of civilians. Seventy one people on the Israeli side, including six civilians, were killed.
Several Egyptian mediated cease-fire attempts failed. Hamas eventually accepted almost the same truce offered at the beginning.
Abbas, whose Palestinian Authority runs the West Bank, formed a unity government backed by Hamas earlier this year. Abbas questioned the future of that arrangement in the interview.
