International teams, including the Red Cross and Egyptian experts, have been allowed by Israel to enter Gaza to search for the bodies of hostages, as efforts intensify to uphold a fragile ceasefire. Hamas has expanded its search for the remains, while Israel has returned the bodies of 195 Palestinians in exchange for 15 hostages' bodies. Despite these efforts, the remains of 13 hostages are still believed to be in Gaza, with both sides accusing each other of not doing enough to facilitate their return. Recent Israeli airstrikes in central Gaza have heightened tensions, with Hamas calling the attacks a violation of the ceasefire and international mediators urging both parties to maintain the truce.
