US blockade strands dozens of Iranian tankers; UANI reports vessels held off coast and Sri Lanka

United Against Nuclear Iran reports that a US blockade is preventing dozens of laden Iranian tankers from departing, with some vessels anchored off Sri Lanka. The claim, if accurate, signals an escalation in US economic pressure on Iran's oil exports, potentially tightening global crude supply. The extent and enforcement of the blockade remain unverified, and the impact on tanker traffic and oil markets is uncertain.
