GAZA, Feb. 13 (UPI) -- Members of the militant group Hamas used medicine bottles delivered to the Gaza Strip to make grenades, an Israeli Defense Ministry official said.
The official said Hamas created the explosive devices to use them against Israeli forces, The Jerusalem Post said Friday.
The bottles were sent by Israel for humanitarian aid, the official said.
"This is another example of Hamas's cynical use of humanitarian supplies to attack Israel," the official said. "Israel facilitates the transfer of the supplies to the Gaza Strip, and Hamas uses the supplies to create weapons."
Israeli forces located several of the undetonated homemade grenades in northern Gaza while taking part in military action against Hamas last month, the Post said.
The newspaper said the use of improvised explosive devices is commonplace in the Gaza Strip.
