A group of OSCE http://ria.ru/world/20140716/1016212924.html (in Russian) monitors arrived on the border between the Russian Federation and the LPR and is trying to find the location of that very "military surplus store", from which tanks, SPH, and SAM roll into Donbass.
An OSCE monitor in Luhansk said that he didn't notice any military installations of the militia in the places where Ukrainian shells hit.
The military attache from the 11 countries that participate in the OSCE visited the suburb of Donetsk in Rostov region, which was subjected to artillery shelling on July 13th from the Ukrainian side. General Schwalb also noted that he is satisfied with the way the Russian side answers to all questions that arise, adding that the military attache will provide a report to the governments of their countries based on the results of the visit.

PS. The way to find a needle in a haystack is to sit down... Military surplus stores just are like that too.
