BERLIN — The Palestinian Authority's ambassador to the Czech Republic died on Wednesday after suffering severe injuries to his arms and legs caused by an explosion at his Prague residence, the police reported. They said there was no indication the explosion had been 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 a safe, according to the online news service novinky.cz.

A police spokeswoman, Andrea Zoulova, confirmed that Mr. Jamal had died in a Prague hospital from the injuries, but declined any comment on the cause of the explosion. The president of the Czech police, Martin Cervicek, was quoted by Czech television as saying "we do not have a single indication that this could be a terrorist attack."

The villa where the explosion took place suffered no damage visible from the outside, according to the online service of the Mlada Fronta Dnes daily newspaper. It quoted neighbors as saying they had heard nothing.

The Palestine Liberation Organization maintains missions in a number of European capitals. The ambassador's residence is different from the mission itself, which is in a neighboring villa.
