Separate accidents on Dubai's arterial roads caused peak hour traffic to come to a standstill this morning.
One accident involved two cars that were overturned on Sheikh Zayed Road.
Motorists posted pictures on social media of two vehicles that had flipped over on the Abu Dhabi-Dubai bound road just before the World Trade Centre underpass.
It was not immediately known if anyone had been injured in the accident.
The second accident took place on Oud Metha road towards the Wafi Bridge, confirmed police. No details were given.
Dubai Police used Twitter to caution motorists: "An accident has been reported on SHK Zayed road before Trade Center tunnel toward Al Garhood Bridge."
Meanwhile, Abu Dhabi Police also reported bottlenecks after the Mussafah Bridge towards the city around 8.10 am but said traffic was back to normal in less than an hour.
