See here (keep clicking "load more" to read the whole story). Some munitions were found with an image of an umbrella (at first folks were saying a crescent) and a six-pointed star. The latter symbol had folks saying the weapons were Israeli-manufactured. Turns out, the umbrella is a parachute icon and the star is a symbol predating the existence of Israel indicating a flare round. The weapon itself was identified as an 81 mm illumination round, probably of Indian or British manufacture.
Alas, the story that Israel is supplying Qaddafi with weaponry has been making the rounds on al-Jazeera and PressTV.
