TUNIS, March 14 (Reuters) - Tunisia plans to issue an international bond of 750 million to 1 billion euros in the second half of April and will begin the process, including sounding out potential demand, at the end of this month, a government official told Reuters on Monday.

The North African country last tapped the international market about a year ago when it issued a $1 billion bond. Tunisia is struggling with lower tourism revenues after three militant attacks last year, protests over unemployment and slow progress on economic reforms.
