There has been a security alert at Istanbul’s main Ataturk airport, with police firing shots after a motorcycle ignored an order to stop. <br /><br /> One of the two men on the bike was wounded and detained, according to reports. The other was caught by police after a pursuit. <br /><br /> It was not immediately clear why the police ordered the men to stop.<br /><br /> No-one else is believed to have been hurt. <br /><br /> Cars were briefly barred from entering and leaving the airport, but flights were not affected.<br /><br /> The incident comes in the wake of an attack at the airport in June, when suicide bombers – suspected of belonging to the so-called Islamic State – killed 41 people and wounded around 240 others, with gunfire and explosives.<br />
