Iranian authorities have issued a directive outlining preparations for a possible US ground assault, according to a report citing a source familiar with the matter, as concerns grow in Tehran over a potential escalation of the war.

The directive, circulated among military and security bodies under Iran’s General Staff, instructs units to increase readiness, secure sensitive sites, and prepare for both external attacks and internal unrest. It also allows certain units to act independently if communications with central command are disrupted, reflecting fears that command structures could be targeted in future strikes.

According to the report, the measures focus on major urban centers and strategically sensitive regions, including southern and northwestern Iran. Officials are also preparing for what they describe as the possible “intervention of hostile elements” across different parts of the country.
