A prominent Philippine senator has created a stir by saying on social media she has knowledge of a Chinese plan to target her country with hypersonic missiles, though the national security council said it was unaware of any such security threat.

Sen. Imee Marcos, the sister of Philippine President Ferdinand Marcos Jr. and head of the senate foreign relations committee, made her claim in a short video that has, so far, had over 900,000 views on TikTok and over 100,000 on Facebook.
