Thermal mugs given to Israeli government offices by the Chinese embassy may have contained a listening device, government sources said on Tuesday.
Then Shin Bet (Israel Security Agency) began investigating the matter after finding a suspicious device in mugs the embassy sent to the Science, Technology and Innovation Ministry and Transportation Ministry. The suspicions were first reported on Tuesday morning by Army Radio’s diplomatic correspondent Moriah Asraf-Walberg.
