TUNIS (Reuters) - Turkey will deposit a $100 million zero interest loan in Tunisia's central bank to support the North African country's struggling economy, Turkey's deputy prime minister said on Tuesday.

The loan was announced at an investment conference in Tunis where Western and regional partners have been offering financial backing.

Tunisia is trying to reverse a decline in foreign investment since its 2011 uprising.
