Dubai emergency services put out a "small fire" after residents reported a loud explosion that shook buildings near Jebel Ali port, Emirati officials said Thursday.
Nobody was hurt in Wednesday night's incident, which came six months after an explosion on a container ship unleashed a fireball at one of the world's busiest ports.
Local residents said nearby buildings shook for about two seconds and they feared their windows would break.
"We felt a shock wave. The windows of my house in Jebel Ali village nearly fell off last night," one Twitter user posted.
"Not sure how small this was, but it definitely generated a shock wave strong enough (for) the house to shake... All the neighbours felt it too."
The July explosion on a container ship carrying flammable materials sent out shock waves that pulsed through nearby Dubai and a fireball that shot into the sky.
Such events are a rarity in the wealthy oil-rich UAE.
