Israeli media report at least eleven people have been killed in twin bus bombings in southern Israel. At least 20 others have been wounded. A third blast was reported, but officials say it was a false alarm. The bus explosions occurred almost simultaneously on the main street of Beersheba. It's not clear whether they were set off by suicide bombers or remote control. The buses erupted in flames -- and windows have been blown out. At least two bodies are on the ground covered in white sheets nearby. Israel Radio says Palestinians carried out the attack. There is no confirmation of that claim. Palestinian Cabinet Minister Saeb Erekat says the Palestinian Authority condemns any attacks targeting civilians, regardless of nationality. Palestinian militants haven't carried out a suicide bombing inside Israel since March. Beer Sheba is 25 miles west of Gaza City.
