Israeli strikes in Gaza killed at least 104 people, including dozens of children, the enclave’s health authorities said on Wednesday, marking the deadliest day since the beginning of the ceasefire championed by US President Donald Trump.

President Donald Trump voiced support for Israel's actions after the U.S. ally carried out strikes across the enclave and traded accusations of truce violations with Hamas.

Israel says it has "renewed enforcement of the ceasefire" after deadly airstrikes in Gaza that tested the U.S.-brokered peace deal.

The strikes, the deadliest since the ceasefire began on Oct. 10, marked the most serious challenge to the tenuous truce to date.

The Israel Defense Force indicated that a ceasefire was being resumed after the Jewish state, a key ally of the United States, executed strikes on Tuesday.

Hamas has claimed the Trump administration's "biased stance" toward Israel means the ceasefire will continue to be violated.

Thirteen families whose loved ones were taken hostage during the Oct. 7, 2023, attack are still waiting for Hamas to return their remains from Gaza.
