Cyprus: likely gas field find raises prospect of tension with Turkey

Expected announcement by ExxonMobil of discovery off island's south coast seen as potential game changer

Tensions between Cyprus and Turkey over energy could soon come to a head, with ExxonMobil apparently poised to announce a significant natural gas find off the divided island's southern coast.

After more than three months of deep-water exploration in the eastern Mediterranean, the US firm is expected to unveil findings this week in what is being described as a seminal moment in the race to tap potentially profitable underwater resources.
