BAGHDAD  The Iranian government said Saturday that an oil field that its troops occupied a day earlier was on its side of the border with Iraq, despite Iraqi claims to the contrary.

A group of about 11 Iranian soldiers seized a portion of the remote Fakka oil field in Maysan Province in southeastern Iraq early Friday, according to Iraq.

Government officials in Baghdad said they had summoned the Iranian ambassador to protest the military action, but diplomatic efforts had so far failed to resolve the dispute.

Ramin Mihman-Parast, a spokesman for the Iranian Foreign Ministry, denied on Saturday that Iranian soldiers were occupying an Iraqi oil field, said the Iranian state news agency.
