The happy couple was supposed to be celebrating their marriage.
Dr. Israa Seblani and Ahmad Sbeih were on the streets of Beirut on Tuesday, with Seblani posing for photos in a dramatic, white wedding gown. It was a day like any other in the city's Saifi Village, she said, with people out and about shopping and dining in restaurants.
Then all of a sudden, there was a loud noise. Seconds later, an eardrum-shattering blast erupted behind her.
That horrifying sound was the massive explosion which rocked the Lebanese capital, leaving at least 135 dead and 5,000 injured. Mahmoud Nakib, the couple's wedding photographer, captured the moment it all went down.
"We were filming an outdoor photo session for (Seblani) and (Sbeih), then we heard an explosion," Nakib told CNN. "That was the first explosion, we thought that is was far away, we continued filming normally."
But that soon changed. "In just one second, the sky turned black and we heard the second explosion," Nakib said.
As the explosion went off, an intense gust of wind created by the its shock wave roared through the square, the video showed.
"The area I was in -- within matter of seconds -- it went from beautiful place to ghost town filled with dust, shattered glass and people yelling [and] bleeding," Seblani told CNN. "It was like a nightmare scene."
Seblani, Nakib and the rest of the wedding party headed inside as the blast echoed through the streets of Beirut. Everyone in the wedding party is doing OK, and no one was hospitalized.
