A large alligator has been captured on video climbing over a fence at a US military air base.

In the footage, the reptile can be seen clawing its way up a fence at the Naval Air Station (NAS) in Jacksonville, Florida.

Once it reaches the top it flops its body over the other side and walks away.

Christina Stewart, who took photos and video of the animal from her car, is heard saying: “There it goes, over the fence!”

On Facebook she said she was “glad I got to watch him or her crawl over the gate and disappear”.

The base said in a Facebook post: “If you are new to Florida or have been here for years, when you see water, assume an alligator could be in it.

“We have several on the base and they don’t respect our security measures.”

It added: “On the serious side, always be aware with small children and pets.

“Golfers be aware and watch where you stick your hands.

“Do not approach them ever!”
