Kuwait has summoned an Iranian envoy to protest Tehran's apparent offer of investment opportunities in the disputed Dorra gas field, state media reported Wednesday, according to AFP.

The move followed a report by the National Iranian Oil Company (NIOC) about investment possibilities in the Islamic republic, which "covered areas located near the Kuwaiti oilfield," the KUNA news agency said.

An official at Kuwait's foreign ministry said Iran's charge d'affaires was summoned on Sunday and was handed a letter of protest, according to the report.
