(CNN)Protesters are expected to rally in cities across the United States this weekend in support of Palestinians, as Israel and Hamas agreed to a ceasefire ending days of destruction and bloodshed.

Since May 10, Israeli airstrikes have killed at least 243 people in Gaza, including 66 children, according to the Hamas-run Ministry of Health. Twelve people in Israel, including two children, died as a result of militant fire from Gaza, according to the Israel Defense Forces and Israel's emergency service.
