A mysterious explosion which killed a Palestinian ambassador to the Czech Republic was apparently caused by a decades-old booby trap.
Jamal al-Jamal, 56, suffered "very serious injuries" in the blast after he opened an old embassy safe at his home. He died later in hospital.
Police said the explosion could have been caused by some kind of anti-theft system, though why the trap was set - and by whom - was unclear.
Spokeswoman Andrea Zoulova described the device as a booby trap and said: "The evidence the police have doesn't suggest anything like a terror attack or that a specific person would set up a system with the intention to hurt or kill anyone."
