TUNIS, Dec 8 (Reuters) - Tunisia will need 8.5 billion dinars ($3.7 billion) in foreign loans in 2017, the finance minister told parliament on Thursday, $1 billion more than previously expected.

Tunisia needs the money to cover a deficit forecast to be about 5.4 percent of gross domestic product next year. The government has also included tax increases and spending cuts in its 2017 budget, which is before parliament.
