Irish casualtiesConcerns were growing last night that an Irish woman may have been one of the people killed in the explosions.
Family members of the woman have been unable to make contact with her, and have asked for the assistance of the Department of Foreign Affairs.
Officials in the Irish Embassy in London are pursuing the case with the British Foreign Office and the emergency services.
The woman, an Irish passport holder who had been living outside out of the State for several years, had been residing in a third country before moving to the UK some time ago.
Meanwhile, a Co Galway man was being treated in hospital yesterday for serious head and arm injuries.
Willie John Walsh (24), of Kylebroughlan, Moycullen, was travelling on the stricken underground train between Liverpool Street and Aldgate. The architect was in a carriage that was ripped apart by the explosion. Seven passengers in the carriage were killed.
His mother, Barbara, who has travelled to London, said: "He doesn't remember much, but somebody broke the windows and he and a girl alongside him got out. I expect he got some of the lacerations from trying to escape through the window, while he had also received burns from the bomb blast itself.
"He was crawling around in the dark, and he remembers stumbling down the tracks to the entrance at Aldgate station. The ambulance people and police then picked him up and brought him straight to hospital.
"He is a bit groggy right now from the surgery, but we are just so relieved that he is OK and will be fine. There are people here with very serious injuries and some have died."
Another Galway man described yesterday how he had a lucky escape. Dylan Lawless, a software engineer working with Emap, was on the way to work on the Circle Line and approaching Edgeware Road station when a bomb exploded on a train which had pulled alongside.
Speaking to Galway Bay FM radio yesterday, he said: "It smashed windows and that kind of stuff, but it didn't pierce the metal of our carriage."
