Hamas fired 60 rockets at Israel today — another bombardment in an aerial assault that’s totaled 6,300 rockets and mortars since Israeli forces left the Gaza Strip in August, 2005. But today’s weapons were different. These weren’t short-range, home-made Qassam rockets that make up the bulk of Hamas’ arsenal. Nor were they the longer-flying 122 mm Grad rockets, designed by the Soviets and made in Iran. Some of today’s rockets flew an alarming 22 miles, hitting an empty school house in Beersheva, the unofficial capital of the Negev Desert region. And they were made in China.
