TEHRAN -- Iran's state broadcaster IRIB said one of its buildings was hit on Monday in a "brutal aggression" by Israel, but added that live broadcasts continued without major disruption.

IRIB said the strike targeted its news network in an apparent effort "to silence the voice of the Iranian nation and the voice of truth." It said staff continued to provide coverage "at full capacity."

Video footage aired by the network showed the moment the attack occurred during a live broadcast. An anchor was seen delivering the news when an explosion was heard. She reported the blast and condemned the strike, but a second explosion and resulting smoke forced her to halt the broadcast.

The anchor later reappeared on camera, uninjured, according to IRIB's live report.

In a major escalation of regional tensions, Israel launched large-scale airstrikes early Friday, killing several military commanders, scientists, and dozens of civilians. Iran responded with retaliatory strikes later that day, and the exchange of fire continued into Monday.
