According to a spokesperson for the National Prosecution Office, there are "to all appearances, a few dozen serious witnesses" who will be questioned. Many of the tips came from eastern Ukraine, where the Malaysia Airlines flight was shot down in July last year.
In particular, the Joint Investigation Team so far received 170 emails, 135 phone calls, one tip via Skype and one tip via the Russian version of Facebook, VK.
It should be noted that at the beginning of last week the Joint Investigation Team has called on witnesses in eastern Ukraine who may have seen anything involving a BUK missile in the days before and after the MH17 crash on July 17th last year.
Earlier this month, a forensic investigation by RTL Nieuws claimed to have found the first clear evidence that flight MH17 was shot down by a Russian BUK missile.
Dutch Safety Board announced its readiness to attach these findings to the investigation.
