The king, whose country is a member of an international coalition battling the Islamic State group, also later met President Barham Saleh.

Iraq in 2017 declared victory over IS following a bruising months-long campaign backed by the coalition, which continues to carry out operations against the jihadists.

Spain, which took part in the US-led 2003 invasion of Iraq that overthrew dictator Saddam Hussein, went on to support Iraqi troops as they battled to roll back IS, which seized a third of the country including second city Mosul in 2014.

Hundreds of Spanish military instructors remain in the country.

King Felipe is one of a series of leaders to visit Baghdad since the start of the year, including US President Donald Trump, who drew criticism for failing to meet a single Iraqi official.

Baghdad has also hosted the chief diplomats of its two main allies, Washington and Tehran -- themselves bitter enemies.

Iraq's precarious position has been complicated by Trump's shock decision last month to pull troops from neighbouring Syria.

That has prompted pro-Iran factions to intensify their calls for an accelerated withdrawal of US troops from Iraq.
