The weapons found at Palestine's embassy in Prague in early January originate from the 1970s and the 1980s, Czech police spokeswoman Andrea Zoulova announced Thursday, and have not been used for criminal purposes. "Ballistic tests of the seized weapons have ruled out their identity with tracks uncovered in the case of as yet unclear crimes committed in the Czech Republic," said Zoulova. "The enquiry into the case continues, as do further expert assessments," She said, adding that the results could be expected in the next few weeks. The Palestinian Ambassador to Czech Republic Jamal al Jamal was killed by a safe explosion on January 1, 2014 in the new embassy building in Prague. The Czech police uncovered illegally kept weapons in the embassy building in the afterwards investigation. The Palestinians explained that the weapons originate from the era of Czechoslovakia and have never been used, they also apologized for keeping the weapons. The Czech police investigate the case as neglect killing and illegal possession of arms though Jamal's daughter mentioned the possibility of her father having been assassinated.
