BERLIN — The Palestinian ambassador to the Czech Republic died on Wednesday after suffering severe injuries caused by an explosive booby trap security system in a safe at his Prague residence that he apparently had triggered by mistake, the police reported. They said there was no indication the explosion was sabotage or a terrorist attack.

The diplomat, Jamal al-Jamal, 56, had been in the Czech capital only since Oct. 11. He and his family were just moving into the residence, and the explosion occurred while he was opening the safe, inadvertently setting off the security protection, according to a police spokeswoman, Andrea Zoulova.

Daniel Langer, the lead surgeon at the Central Military Hospital in Prague, said the ambassador had suffered head, chest and stomach injuries. The immediate cause of death will be confirmed during an autopsy.

An unidentified 52-year-old woman was taken to the hospital from the residence after apparently inhaling fumes from the explosion, but she was released soon afterward, said Jirina Ernestova, an official in Prague’s emergency services.
