Czech police said Thursday investigators have discovered another explosive at the Palestinian embassy complex in Prague where a possibly booby-trapped safe killed the ambassador.
A spokesman, Tomas Hulan, confirmed the discovery on Thursday, adding that the unidentified explosive had been sent for testing to Prague's Institute of Criminology. He declined to give details.
Police had already found 12 illegal weapons in a search following the explosion on 1 January, prompting the Czech foreign ministry to accuse the Palestinians of breaching international obligations. The Palestinians said the weapons were not illegal and dated to the cold war.
The ambassador, Jamal al-Jamal, died after the safe exploded. The career diplomat had only started his posting in October.
It remains unclear what caused the safe to explode, but the ambassador's death is being investigated as a case of negligence.
