Turkey's prime minister has promised to promote national unity and fight terrorism after his ruling Islamist party comfortably won parliamentary elections. With nearly 100 percent of the vote counted, Recep Tayyip Erdogan's Justice and Development party, or AKP, claimed a new five-year mandate after it won 46.6 percent of the vote, Turkish electoral officials reported Monday. Though its share of the vote was larger than it was in 2002, when it was voted into power, Turkey's system for apportioning parliamentary seats means it will hold 342 seats in the country's 550-seat parliament, down from the 363 it now holds, the Associated Press reported.
