The group said in a statement that it was "doing everything possible to keep the occupation's captives alive, but the random Zionist (Israeli) bombardment is endangering their lives".

"Every time the occupation attempts to retrieve its captives by force, it ends up bringing them back in coffins," it said.

Israel restarted intense air strikes across the densely populated Gaza Strip last week followed by ground operations, shattering the relative calm afforded by a January ceasefire with Hamas.

Since Israel resumed its military operations in Gaza, at least 830 Palestinians have been killed, according to the health ministry in the Hamas-run territory.

The war was sparked by the militant group's October 7, 2023, attack on Israel, which resulted in the deaths of 1,218 people, mostly civilians, according to an AFP tally based on official figures.

Israel's retaliatory military offensive has killed at least 50,183 people in Gaza, mostly civilians, according to the health ministry.
