Intelligence agents raided an Afghan refugee camp on the outskirts of Peshawar and arrested two alleged Islamic militants, a security official said on Thursday. It wasn't clear what prompted the authorities to raid the Jalozai camp, the official said, adding that they had been picked up late on Tuesday and were being questioned. Another government official confirmed the arrests but could offer no further details. On Wednesday, provincial Governor Syed Iftikhar Hussain Shah visited Wana to thank tribal elders for supporting the military in its operations against militants. Security officials believe that scores of Arabs and Central Asians are hiding in South Waziristan.
