Philippines accuses China of using cyanide to poison South China Sea atoll

The Philippines has accused China of using cyanide to poison the South China Sea near Second Thomas Shoal, a disputed atoll in the Spratly Islands. Philippine security officials claim laboratory tests confirmed the presence of cyanide on Chinese boats seized last year. They warn the cyanide could harm marine life, weaken the reef, and deprive Filipino navy personnel stationed there of a food source. The Philippines grounded a warship on the atoll to reinforce its maritime claim. China's Foreign Ministry has dismissed the accusation as a "stunt," claiming the Philippines illegally harassed Chinese fishing boats. This accusation comes amid ongoing tensions between the two countries, including recent incidents where China disrupted resupply missions to Filipino troops stationed on the grounded warship.
