PRAGUE – Police say they discovered a total of 12 illegal weapons at the Palestinian embassy complex where a possible booby-trapped safe killed the ambassador.

Police spokeswoman Andrea Zoulova declined to provide more details on Sunday, citing an ongoing investigation.

Ambassador Jamal al-Jamal, 56, died Wednesday after an embassy safe exploded. The career diplomat had only started his posting in October.

It remains unclear why there were unregistered weapons at the embassy and what caused the safe to explode. The death is being investigated as a case of negligence.

Residents in the Suchdol district, where the new embassy complex is based, have lodged security concerns over the incident.
