July 28 (Reuters) - Seven Walmart stores in Missouri were evacuated after receiving bomb threats but no explosives were found, a Walmart spokesman said on Saturday. The threats were called in late on Friday to stores in Raytown, Gladstone, Jefferson City, Nixa, St. Peters and Ozark, spokesman Dan Fogleman said. The retailer is working with police to find those responsible, Fogleman said. No explosives were found and no injuries were reported.
Seven Walmart stores in Missouri received telephone calls warning them of bombs planted at their work place
It says in the context the seven walmarts received bomb threats, but it does not say how they received the bomb threats.  So the Statement " seven walmart stores received telephone calls warning them of bombs" is neither definitely correct, nor definitely incorrect.
