The Israel Defense Forces (IDF) says there is a "high probability" that three Israeli hostages found dead months ago were killed in an Israeli air strike.

The IDF announced the conclusions of its investigation into the deaths of Corporal Nik Beizer, Sergeant Ron Sherman and Elia Toledano on Sunday.

It said investigations had determined that the three were likely killed in an IDF air strike in November that also killed a senior Hamas militant, Ahmed Abu Ghandour.

All three of the hostages were kidnapped in Hamas' October 7 attack.

Their bodies were recovered in December, but the cause of death was only recently determined.

In its report, the IDF said there was a "high probability" they were killed in the strike based on where the bodies were recovered, pathological reports and other intelligence.

However, it added, "It is not possible to definitely determine the circumstances of their deaths".

The conclusions could add pressure on the government to strike a deal to bring home the remaining hostages held by Hamas.

Critics say it is too difficult and dangerous to try to rescue them.
