From Newsweek:
Israel struck southern Gaza on Sunday, according to the Israeli military, after accusing Palestinian militant group Hamas of a “blatant violation” of the first stage of the U.S.-brokered ceasefire agreement.
The Israel Defense Forces (IDF) said in a statement “terrorists fired an anti-tank missile and gunfire toward IDF troops” in the Rafah area of southern Gaza. The IDF said when contacted for clarification the statement referred to Hamas operatives. The military said it had started “striking in the area” and said this was a “a blatant violation of the ceasefire agreement.” Hamas has said it is committed to the ceasefire and has accused Israel of breaching the ceasefire.
