A senior Hamas official showed the BBC a list of 34 hostages that the Palestinian movement says it is ready to release in the first phase of a potential ceasefire agreement with Israel.
It is unclear how many hostages are still alive.
Among those whose names were mentioned were 10 women and 11 hostages between the ages of 50 and 85, as well as young children that Hamas previously said were killed in an Israeli air strike.
The list also includes a number of hostages who Hamas says are sick.
Reports from Hamas-run Gaza say Israeli air strikes killed more than 100 people there over the weekend.
The Israeli Prime Minister's Office denied reports that Hamas had provided Israel with a list of hostage names.
Ceasefire negotiations resumed in Doha, Qatar, over the weekend, but the talks do not appear to have made much progress so far.
A Hamas official told Reuters news agency that any agreement to return the Israeli hostages would depend on an agreement for Israel's withdrawal from Gaza and a permanent ceasefire or end to the war.
The official, who requested anonymity, said, “But until now, the occupation remains stubborn about reaching an agreement on the issues of ceasefire and withdrawal, and has not taken any step forward.”
previously, Hamas published a video clip of Israeli prisoner Liri Albag (19 years old). He urged her government to reach an agreement.
She was captured along with six other female soldiers at the Nahal Oz military base on the Gaza border during a Hamas attack on October 7, 2023.
On that day, militants led by Hamas attacked southern Israel, killing about 1,200 people and taking 251 others hostage.
The Israeli military campaign to destroy Hamas had killed at least 45,805 people in Gaza as of Saturday, according to the Hamas-run Health Ministry in the Strip.
The same source says that Israeli air strikes killed 88 people in Gaza on Saturday, while on Sunday, Reuters news agency quoted health sources as saying that 17 others were killed in four separate Israeli attacks on the Strip.
The Israeli military said on Sunday that its air force attacked more than 100 “terrorist” sites across the Gaza Strip over the weekend, killing dozens of Hamas activists.
