What's this snake species & is it venomous?

Hi Aman, and welcome to us :-) Great to see that you are using eBird as well. I'm not sure of the ID, but hopefully someone will. Here is a list, with links to photos of snakes in the UAE: https://www.uaebirding.com/reptiles

This is probably a saw scaled viper ( echis carinatus). And it is quite venomous

Thanks Sameer.
