The IDF and Shin Bet uncovered 6.5 tons of potassium nitrate hidden in sacks that were disguised as aid from the European Union, the army announced on Saturday. Security forces discovered the stash in the cargo of a Palestinian truck at a West Bank checkpoint earlier in December. According to the IDF, the material, hidden in sugar sacks, was planned to be used by terrorists in the Gaza Strip. "Potassium Nitrate is a banned substance in the Gaza Strip and the Judea and Samaria region due to its use by terrorists for the manufacturing of explosives and Kassam rockets," the IDF spokesperson wrote in a statement. "This is another example of how the terror organizations exploit the humanitarian aid that is delivered to the Palestinian population in the Gaza Strip with Israel's approval," the statement read.
