Jamal Al Jamal, the Palestinian ambassador, was mortally wounded Wednesday when something exploded as he opened a safe. Andrea Zoulova, a spokeswoman for Prague police, said a search of the residence turned up weapons not registered in Czechoslovakia, the Czech news agency CTK reported.
"The police have ruled out a criminal act or foul play targeting a specific person," Zoulova said.
After the blast, rumors circulated about the safe. Nabil El Fahel, an embassy spokesman, told CTK the safe Jamal was opening was one used by the ambassador for payroll, operating expenses and documents that needed to be secured.
Another safe in the embassy had not been used for two decades, Fahel said. But police who opened it found it to be empty.
Zoulova said the weapons found in the embassy are now being investigated.
