PRAGUE, Jan. 4 (Xinhua) -- The remains of Palestinian ambassador to the Czech Republic Jamal al Jamal, who was killed by a safe explosion in the embassy's new seat on Wednesday, will probably be flown to the Palestinian territory on Monday, said the embassy's spokesman Nabil Fahel on Saturday.

Meanwhile, Jamal's daughter Rana said that she would not disclose the date of her father's funeral which has already been set.

Experts from the Czech Criminology Institute continued to examine the exploded safe.

"We are examining the exploding substance as well as the safe itself, its lock mechanism," said the institute's deputy director Martin Kotrly.

Police have found dozens of unregistered weapons at the Palestinian embassy. Former Czech military chief-of-staff Jiri Sedivy said on Saturday that Palestinians may have used Prague for weapons transit. The Palestinians promised to check whether previous operation in the Czech Republic was consistent with the Czech legal order.

The Czech police have ruled out a third person's fault and they are investigating the event as neglect killing. But Jamal's daughter Rana is convinced that her father was murdered.
