Germany's Hapag-Lloyd has seen profits slide and doubts it will hit its high-end earnings forecast for the full year.

The Hamburg-based liner operator said group profits slid to €25m ($27m) for the quarter ending 31 March 2020, down from €96m in the previous corresponding period.

The drop was blamed on higher bunker prices after the introduction of IMO 2020 rules at the start of the year.
