Without any other identifying features, it is hard to tell. I would pin it down to one of three things, though.
A walnut, sumac, or ash tree. Unfortunately, without any information on the tree, such as what country the tree is located (I'm not familiar with climate zone hd8, as we use a single number, single letter system here in the US Example: 5a) the smells of the leaves or bark, or any other information that you can give. The closest I can get you is the three that I have mentioned here.
