Growing support for stricken Alfie Evans has spread to Poland, following early interventions from the Vatican and Italy.
Alfie's parents have been embroiled in a legal battle to get treatment for their son who has been cared for in Liverpool's Alder Hey Hospital.
Poland's President Andrzej Duda tweeted on Wednesday that "Alfie Evans must be saved".
Alfie Evans must be saved! His brave little body has proved again that the miracle of life can be stronger than death. Perhaps all that's needed is some good will on the part of decision makers. Alfie, we pray for you and your recovery!— Andrzej Duda (@AndrzejDuda) April 25, 2018
A pile of flowers, toys and candles has grown in front of the UK embassy in Warsaw amid sympathy for the sick child's plight in the Catholic nation.
Pope Francis has appealed for the boy's parents' wishes to be heeded, saying only God can decide who dies.
Italy has offered citizenship to Alfie in an attempt to smooth his path to treatment in the country.
His parents wanted to take him to Rome for treatment with the Bambino Gesu Hospital said to be a possible destination.
