Italy is closely monitoring the political situation in Tunisia, where it sees risk of having to pay higher gas transit prices, two sources told Reuters on Wednesday.

Tunisia could ask to revise upwards the level of rights (on gas transit for Eni's TTPC gas pipeline), a government source said.

The government and Eni are monitoring the situation, the source said.

Another source familiar with the situation said Tunisia could ask to raise gas transit rights that are paid in gas, because gas prices have fallen recently.
