Responsibility of the employer for expenses of employees in pandemic

I am working in a company which is registered in Creative City Fujairah Freezone. Last month, our employer sends us on unpaid leave from April to September.

He said he will provide tickets to return back to my country but suddenly the lockdown was imposed. I didn't sign any extra document and this discussion happened on Whatsapp.

On May, I asked for the accommodation cost but he said he won't pay anything, not even for the food and for the rent which I have to pay. I am now helpless, I don't have money to survive here.

Isn't he responsible for the rent and food cost until I leave the UAE?

Please guide.
