The vehicle's burning first-stage appears as a bright white dot in the flight video.
Around two minutes after launch, the rocket experienced an anomaly and deviated from its course.
A voice can be heard in the background saying: "The launcher's signal is of course being followed at all times".
"There's a station here at the base just behind us in Jupiter called Galileo".
The mission's failure was confirmed nine minutes after liftoff.
"On behalf of Arianespace, I wish to express my deepest apologies to our customers for the loss of their payload and telling them how sorry I am", finished Fabreguettes.
The Arianespace statement said that a data analysis had begun, adding that an independent inquiry commission was to be set up in the hours ahead.
The second stage engine was supposed to fire for 77 seconds and make way for the liquid-fueled third and fourth stage rockets.
Spaceflight Now, a popular space news outlet, tweeted: "Arianespace's live webcast of tonight's launch has started".
This launch trajectory of the Arianespace Vega rocket VV15 shows an apparent deviation (in yellow) from its planned trajectory (shown in green) during the launch of the UAE satellite FalconEye1 on July 10, 2019.
Falcon Eye 1 satellite successfully blasted off to space at the Guiana Space Centre in French Guiana this morning.
The Emirati satellite, Falcon Eye 1, was a dual-purpose Airbus-built model created to supply imagery for the UAE Armed Forces and the commercial market while orbiting Earth 15 times per day.
The rocket had been carrying a satellite known as FalconEye1 - the first of two that will make up the UAE's FalconEye satellite system. However, it is likely that the launch of the second-dubbed Falcon Eye 2-will be moved as a result of the incident.
