Israel struck Huthi targets in Yemen on Friday, including a power station and coastal ports, in response to missile and drone launches, and warned it would hunt down the group's leaders.

Pope Francis on Thursday bemoaned the "ignoble humanitarian situation" in Gaza and said he saw the risk of a world war rising in an New Year audience with the Diplomatic Corps accredited to the Holy See.
