The Turkish army's War Academy students march during the celebration of the 84th anniversary of the Turkish republic in Ankara Monday. Tanks and other military gear paraded during the day, and Turks held torchlight marches into the night to mark the day, which comes amid the government's threat to order a major offensive against rebel bases in northern Iraq. In an address to the nation, Turkey's president pledged to remain resolute in the fight against rebel Kurdistan Workers' Party. On Monday, Turkish helicopters fired rockets at Kurdish rebel positions in mountains near the Iraq border in one of several clashes.
