Demonstrators are still demanding a new election in Israel, just hours after Israeli military forces freed four hostages held by extremist Hamas.
At a government-critical rally in Tel Aviv, a former Israeli military intelligence chief, Amos Malka, referred to Saturday's operation as "an incredibly successful operation in a sea of strategic failures".
Police in Tel Aviv used water cannons to disperse protesters. 33 people were arrested in the city during the evening and night into Sunday.
In Jerusalem, hundreds blocked the intersection outside Prime Minister Benjamin Netanyahu's residence. "We don't want anyone else to die, it's time for an agreement!" the protesters chanted.
The release on Saturday was extremely bloody, with over 200 deaths on the Palestinian side, according to Hamas sources.
Protests were also held in Jerusalem, Caesarea, and Herzliya, The Times of Israel reports.
The demonstrations are bringing together people who are demanding alternative strategies to free the hostages and groups that have previously criticized Prime Minister Netanyahu and his government.
