Israeli authorities have made no arrests in the Aug. 16 daylight firebombing of a Palestinian taxi, which left the driver and four members of a Palestinian family so severely burned that they remain hospitalized, but they have said they suspect Jewish extremists. The incident was denounced by Israeli Prime Minister Benjamin Netanyahu, who vowed to find the perpetrators, and Deputy Prime Minister Moshe Yaalon, who called the beating and firebombing “terrorist attacks.”
