Islamic State militants are believed to have attempted to attack the re-election inauguration of Afghanistan's president, Ashraf Ghani.
A Reuters camera was there for the moment of panic, as explosions hit nearby.
The rockets fell outside the immediate area of the ceremony. It's not yet clear what, if any, damage was caused.
Foreign officials were in attendance including European diplomats, the U.S. special envoy, Zalmay Khalilzad, and the American NATO commander General Scott Miller.
As the rockets fell a defiant Ghani urged calm, continued his speech, and was eventually sworn in to a cheering crowd.
The incident comes just days after the U.S. troop withdrawal agreement was signed with the Taliban.
The Taliban haven't attacked any foreign troops in Afghanistan since the signing, but they continue to attack Afghan government forces.
This isn't the first suspected activity from Islamic State in recent days, either.
On Friday (March 6) they claimed an attack on an event by Ghani's chief political rival, Abdullah Abdullah, that killed dozens.
Abdullah escaped unharmed. And as Ghani's inauguration unfolded on Monday (March 9) Abdullah held his own rival inauguration in a separate event.
Both men say they won the disputed Afghan presidential election and have refused to back down.
