The end of most Covid-19 restrictions was followed by the outbreak of war on Europe's eastern edge, while later in the year Ireland mourned the loss of life in a Donegal explosion. Here are some of the pictures that defined 2022.
24 February: Traffic out of Kyiv on the first day of war, after Russia launches missile strikes in Ukraine. After a week of speculation about Russian leader Vladimir Putin's plans to invade Ukraine, residents wake up to air raid sirens and take shelter underground or make plans to flee.

He and Ukrainian President Volodymyr Zelensky then hold a press conference in the capital.
18 September: Forensic technicians carry a body bag at a mass grave in a forest on the outskirts of Izium, eastern Ukraine. After Russian forces retreat from the area, Ukrainian authorities discover more than 400 graves in the forest, with most bodies showing signs of a violent death. Ukraine says it and other mass graves found in formerly Russian-held areas are proof that war crimes have been committed.

12 January: Ashling Murphy, a 23-year-old teacher, is killed while out for a run along the banks of the Grand Canal in Tullamore, Co Offaly. The death triggers an outpouring of grief, with vigils held across the country, as well as a nationwide discussion on women's safety.

11 July: The James Webb Space Telescope, the most powerful observatory to be placed in orbit, reveals the "deepest and sharpest infrared image of the early universe" ever taken, going back 13 billion years, NASA says.

It is the first in a series of pictures released that week. "This telescope is one of humanity's great engineering achievements," says Mr Biden.
4 August: Europe bakes in its hottest summer on record, with the continent facing multiple heatwaves and what the European Commission says is the worst drought in centuries.
