Netanyahu reiterates opposition to Palestinian state

The most recent remains transferred to Israel from the Gaza Strip match neither of the two hostages thought to be held by Hamas, the Israeli Prime Minister’s Office said on Wednesday.

The remains returned on Tuesday "are not linked to any of the deceased abductees," Prime Minister Benjamin Netanyahu’s office said, citing findings from the National Center for Forensic Medicine.

Further information about the remains was not immediately released.

Netanyahu’s office said the families of the two remaining hostages in Hamas hands, both of whom are presumed dead, were notified of the findings.

"The effort to return them will not stop until the mission is completed -- to bring them to a proper burial in their country," Netanyahu’s office said on Wednesday.

Two people were shot and killed by Israeli forces in Gaza on Monday in two separate incidents, according to the Israel Defense Forces.

The IDF said the individuals crossed into the Israeli-controlled part of northern Gaza "posing an immediate threat" to troops.

"IDF troops in the Southern Command remain deployed in accordance with the ceasefire agreement and will continue to operate to remove any immediate threat," the IDF said in a statement.

The International Red Cross is working in Gaza to help identify remains of those killed during the war, the group said on Monday.

"In Gaza, thousands do not know the fate and whereabouts of their loved ones," the group said on social media, sharing photos of what appeared to be mass graves.

The remains of two hostages are also thought to still be in Gaza, according to Israeli officials. The dead and missing "must be handled respectfully and their dignity protected" under international humanitarian law, the group said.

"The ICRC supports forensics and health authorities to manage, document and trace the deceased so families can find closure," the Red Cross said.
