The Geneva-based Association Aidforall (website www.aidforall.ch) is a small group that does good things. A lot is posted on their website including a short film made by a professional filmmaker who accompanied them on their last trip to Poland and the border. They have made 3 trips so far and are planning the 4th. They are regularly receiving requests from Warsaw and Ukraine for items such as food, hygiene products, medication and surgical items, most recently from Kyiv for a hospital helping rape victims. 

Please take a look at their site, you can donate there, contact them. They are doing good work (they pay for all their own travel, accommodation etc. out of their own money!).

best wishes
