Iran's state TV reports that search teams have found two more bodies of victims from last week's deadly building collapse in Tehran.

The Wednesday report quotes Jalal Maleki, spokesman for the fire department, as saying the bodies belong to firefighters killed in the disaster.

At least 20 firefighters were killed in last week's collapse. On Monday, search teams found four bodies that were not firefighters.

Authorities have yet to offer definitive casualty figures. So far, only seven bodies have been retrieved.
