Iran declares war against the US and Israel, calling them killers of children, civilians and new born babies in Iran.

The claim that Iran has declared war against the US and Israel and accused them of killing civilians, including children, is mostly true because multiple reliable sources confirm active hostilities and strong condemnations by Iran, though no formal war declaration document is explicitly cited in the sources.

The reporting

What the Evidence Shows

Multiple authoritative sources document an ongoing and intense conflict between Iran, the United States, and Israel during 2025-2026. Iran has launched missile and drone strikes targeting US military bases, embassies, and Israeli interests in retaliation for attacks by the US and Israel.commonslibrary.parliament.uk justsecurity.org The conflict has involved significant civilian casualties in Iran, including children, which Iran and other observers have highlighted as part of their condemnation of US and Israeli actions.+2 more

Public demonstrations in Tehran have included burning US and Israeli flags, reflecting strong official rhetoric against these countries.nbcnews.com While the sources confirm Iran’s military response and harsh accusations labeling the US and Israel as responsible for civilian deaths, none explicitly provide a formal declaration of war document or statement from Iranian leadership using the exact phrase "declares war.

" Instead, the situation is described as an active war or conflict with reciprocal strikes and severe rhetoric. Therefore, the claim is supported in essence but lacks confirmation of a formal legal declaration of war.
