Dozens of Jews from Kiryat Arba and neighboring Har Hevron communities blocked roads in their vicinity to Arab traffic this morning. This was in response to yesterday\'s opening of many roads that had long been closed, for security reasons, to Arab drivers. Some 30 residents of Tapuach (central Shomron, east of Ariel) burst into the Ariel police station last night to free their friends who had been arrested earlier on suspicion of planning violence against Palestinians. They uprooted the station gate and scuffled with policemen; three of the latter were hurt, and four Tapuach residents were arrested.
