(Reuters) - Tunisia will sign project financing deals worth some 10 billion Tunisian dinars ($4.3 billion) at an investment conference being held in Tunis, a senior Tunisian official said on Tuesday.

Tunisia has received pledges of financial assistance from foreign governments at the conference but is also hoping to secure long-term investments that can help it reduce unemployment and boost growth.
