Israel has confirmed pumping seawater into Gaza's tunnels, a move that could violate international law and have dire consequences for the enclave's freshwater supply. Environmental analysts warn that this could damage Gaza's groundwater aquifer, which 2.3 million people depend on, leading to long-term devastation. The region already faces water scarcity and sewage contamination, and the flooding of tunnels could exacerbate these issues. The move has raised concerns about Israel's use of water as a weapon and potential violations of international law, including the UN Genocide Convention.
