The happy couple were meant to be celebrating their marriage.

Dr Israel Seblani and Ahmad Sbeih were posing for their wedding photos on Tuesday on the streets of Beirut.

Starting off as a perfectly normal day, Dr Seblani posed in a beautiful, white wedding gown in the city’s Saifi Village.

Then all of a sudden, there was a eardrum-shattering noise that came from behind her.

The horrifying sound was the massive explosion which rocked the Lebanese capital, leaving at least 135 dead and 5000 injured.

The couple’s wedding photographer, Mahmoud Nakib, captured the moment it all went down.

“We were filming an outdoor photo session … then we heard an explosion,” Mr Nakib said.

“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,” Mr Nakib said.

As the explosion took place, an intense gust of wind tore through the square, as captured in the video.

“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,” Dr Seblani said.

“It was like a nightmare scene.”

The shockwave pushed Mr Nakib down the street, he said, nearly knocking him over.

But his camera kept rolling, documenting the chaotic scenes taking place around him.

Dr Seblani, Mr 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 hospitalised.

“I thought first of my wife and my daughter,” Mr Nakib said thought as he ran for cover.

“I called her to let her know that I'm fine and do not go out.

“And I went live at Facebook to let people know what happened.”

The explosion in Beirut wiped out entire city streets and left hundreds of thousands without homes.

It has been linked to a warehouse storing thousands of tons of an unsecured and volatile chemical compound.
