I'd say Chrysops flavipes, but it is pretty yellow.
I have to check

Chrysops flavipes is the only species of the flavipes-group recorded from Israel.
So flavipes it is.

Many thanks for the id :D
As I understand this fly feed on blood, but I found it in the middle of a coastal city. No big mammal in the area. How do you think it is feed? Maybe Human, dogs etc.. ?

First choice host would be cattle of any kind.
Please understand that these horseflies can fly kilometers finding their host. I'm sure there will be for instance goat present within 5 km?

Ok, If we are talking on a radius of 5km so yes I guess it can find cattle. Now when thinking on it I guess it can also find animals at a distance of merely 2km by visiting at the zoo.

Some species tabanids never feed on blood - they are autogenous.
Some species always need a blood meal to produce a batch of eggs - these are anautogenous.
Some species can lay one batch of eggs without having a blood meal but require a blood meal for subsequent egg laying.
Your fly may fit into the latter group; they are able to survive as a population in areas lacking or having very sparsely distributed mammals; coastal species would benefit by being autogenous.
