The authorities gave no indication of foul play in the blast that killed at least two people, wounded 120 others and damaged several buildings and stores.
At least two people have been killed and 120 injured in a gas cylinder explosion in a restaurant in the United Arab Emirates capital, Abu Dhabi.
Initial reports after Monday's incident "showed that 64 people sustained minor injuries, 56 others were moderately wounded, and two people died", police tweeted.
The blast set off a fire that damaged the facades of six buildings and a number of stores before being brought under control, they added.
Four of the damaged buildings were "safely" evacuated, with efforts underway to find their residents temporary housing "until the buildings are completely secured", the police said.
A witness told The National newspaper that he heard two explosions around lunchtime in the Khalidiya district of Abu Dhabi.
"The first sound was small and people started calling the fire and police," said the man, who was not identified.
"Then soon, there was a big blast. It was a really big sound. The windows shook and in some offices, the windows shattered."
The authorities gave no indication of foul play.
However, the UAE has been on heightened alert since a Yemen rebel drone and missile attack killed three oil workers in Abu Dhabi on January 17.
Authorities have since thwarted three similar attacks, including one claimed by a little-known group believed to have ties with pro-Iran armed factions in Iraq.
The UAE is part of a Saudi-led military coalition that has been fighting in Yemen since 2015 to support the government against Iran-backed Houthi rebels, who control the capital Sanaa.
