A question about visa-free periods of travel to Belarus

Hello! Unfortunately, the US embassy has not answered the question in the e-mail, and so I am hoping to receive some advice here. As I understand the current rules and conditions, it's possible for US and other foreign citizens to spend a maximum of 5 continuous days in Belarus without the visa, however the number of visa-free entries is not specified. Does anyone know if it's possible for the foreign citizen to use this option more than once per year? As a hypothetical example, would it be possible to spend 5 visa-free days in Minsk during the month of April, and to also spend another 5 visa-free days in Minsk later during the month of June?? Thank you in advance for your consideration and help<span class='ns ns_128522'>&nbsp;</span>
