Kuwait's foreign minister has flown to Iraq for the highest-level visit since Iraq's armed forces invaded its southern neighbour in 1990.

Sheikh Muhammad al-Sabah, who is also Kuwait's deputy prime minister, met Iraq's PM and other top officials.

They discussed joint oilfields, maritime borders and war reparations, exactly 19 years after Iraqi forces were expelled from Kuwait.

Iraqi officials said it was "illogical" to continue paying Kuwait compensation.

Many countries have written off their debts to help Iraq get back on its feet since the overthrow of Saddam Hussein by a US-led invasion in 2003.
