PROTESTERS stormed the streets of Turkey’s biggest cities yesterday as a deepening corruption scandal threatened to bring down the government and sparked fears of a military coup. Riot police fought back with water cannons, tear gas and rubber bullets in Istanbul’s Taksim Square six months after violent scenes in the city over Turkey’s shift away from its leanings to western democracy. To cries of “catch the thief”, a slur aimed at prime minister Recep Tayyip Erdogan, protesters threw rocks and firecrackers as riot squads attempted to block demonstrators from taking over the square. At least 70 were arrested.
