Can you identify this climbing plant?
Based on the fruits, leaves and tendrils, it looks quite like Bryonia dioica (which is toxic). It is almost certainly something from the same family (Cucurbitaceae, which often make such tendrils and usually have similar leaf shapes) and could even be the same genus, Bryonia, which is present in the Mediterranean region (there's even a cretica species). Based on images found on the internet, leaf shape seems variable (more or less indented).
