It was an M-75 hand grenade. Manufactured in great numbers for the Yugoslav national army, and then seized by paramilitaries during the civil war in the 1990s, the grenades are packed with plastic explosives and 3,000 steel balls, well suited for attacks on enemy trenches and bunkers.

So reports the New York Times.  Zuniga died; his wife, Wanna, peddling ahead of him was also blown off of her bicycle, shrapnel penetrating her body.  Trying to crawl back to her husband, she was stopped by the police who happened to be nearby.  The explosion shuddered windows 50 feet away.

According to the Times, "Much of the problem is the supply of surplus weapons."  Wait a minute.  These "surplus weapons" have been available since the 1990s.  But when did this use of hand grenades begin?
