Iranian President Hassan Rouhani has visited the site of the collapsed Plasco high-rise in downtown Tehran to inspect the ongoing search and rescue operation there.

Speaking to reporters on Saturday morning, Rouhani stressed that the search and rescue operation should continue until all those trapped under the rubble are saved.

Up to 30 people, all of them most likely firefighters, are believed trapped under the rubble of the building, which caught fire early on Thursday and came down hours later.

Rescuers have been using life detection devices to locate possible survivors, and, according to the Mehr news agency, at least four responses have been picked up, likely indicating that at least four people are still alive.
