The White House claims Russia has obtained a “troubling” emerging anti-satellite weapon but cannot directly cause “physical destruction” on Earth. US President Joe Biden's national security chief will now brief top lawmakers after they warned of a "serious" national security threat. US Secretary of State Antony Blinken said the threat is not yet "active” but “it is a potential one that we're taking very, very seriously”. Experts say if Russia were to deploy nuclear warheads to destroy US satellites, the consequences could be catastrophic. However, Russia slammed Washington’s concerns as a "malicious fabrication” and a ploy to try to pass the Ukraine aid package stalled in Congress.
