A grenade blast apparently set off inadvertently wounded 16 people in a public place Thursday in Puerto Vallarta, in the western Mexican state of Jalisco, dpa reported. Cristina Guzman, a spokeswoman for the Jalisco State Attorney's Office, told the German Press Agency dpa that five of the injured have serious wounds. One victim suffered the amputation of a leg and another lost a foot. These same five people who were most seriously wounded have been arrested, because the explosion early Thursday came from their table, where the grenade's safety pin was also found.
