At least 18 people were killed and 24 others injured after airstrikes hit residential areas in Iran’s Alborz province on Tuesday, according to Iranian media reports, as the conflict involving Israel, Iran, and allied forces continues to intensify.

Iran’s semi-official Mehr News Agency reported that the strikes targeted housing units in populated neighbourhoods, raising fresh concerns over civilian safety as the war expands deeper into urban regions.

The full extent of the damage is still being assessed.

The latest attack comes amid a sharp escalation in hostilities across Iran, with multiple cities witnessing air raids in recent days.

Reports indicate that residential areas around Tehran, including Alborz province, have increasingly come under fire, marking a shift from strategic and military targets to densely populated civilian zones.

Earlier strikes across Iran had already caused significant casualties, with local media reporting deaths in areas such as Shahriar and Pardis following similar attacks on neighbourhoods.

The broader conflict has spiralled into one of the most volatile phases in recent years, with Israel carrying out repeated strikes on Iranian territory and Iran responding with missile and drone attacks across the region.

Civilian infrastructure, including homes and transport hubs, has increasingly been caught in the crossfire.

International concern is mounting as civilian casualties rise. Global leaders and humanitarian agencies have warned of a worsening humanitarian crisis if strikes on populated areas continue, urging immediate de-escalation.

With no ceasefire in sight and tensions escalating across multiple fronts, fears are growing that further attacks on civilian areas could deepen the crisis and widen the regional conflict.
