Istanbul-based Turcas Holding has offered Israel, which has started to discover considerable amounts of natural gas in the eastern Mediterranean, to build a pipeline under the sea from Israel to Turkey’s southern province of Mersin. A member of the board, Mathew Bryza announced the offer worth $2.5 billion during an energy conference held in Greek Cyprus. The 470-kilometers-long pipeline would have a capacity to transfer 16 billion cubic meters of natural gas a year.
