Is Israel flooding seawater into Gaza tunnels? This is what Biden has to say

Israel's military has initiated the pumping of seawater into Hamas's extensive tunnels in Gaza, according to reports. President Biden has expressed concern about potential civilian impacts but has not officially confirmed the report. Within the Biden administration, there are mixed opinions on Israel's tunnel flooding tactic. The Wall Street Journal has detailed various methods considered, including airstrikes, liquid explosives, dogs, drones, and robots. Water pumps near the Shati refugee camp have been set up by the IDF for potential tunnel flooding, supported by the IDF chief. Environmental concerns have been raised over aquifer contamination and soil impact risks. Egypt previously flooded Gaza's tunnels, resulting in environmental damage and complaints from Gazans. In the late 2000s, 22,000 Palestinians worked in the tunnel industry, with Hamas imposing taxes on shipments passing through.
