Turkey has warned that it may reduce economic and Defence ties with Israel following the deadly raid on a Gaza aid flotilla. Deputy Prime Minister Bulent Arinc said Ankara was assessing deals with Israel, once its close ally. Nine Turkish activists were killed when Israeli troops clashed with passengers on a ship trying to break its blockade of Gaza on Monday. However, Israel said it had a duty to stop the flotilla and ensure weapons were not being smuggled into Gaza. <br/>
