under most countries laws, if their are foreigners within the borders who are hurt or injured in someway, without other proper financial means, it's the responsibility of the government to accommodate the foreigner. for example, in italy, people visiting will have the same access to free healthcare as citizens of italy.
anyway, the whole situation was a result of poor infrastructure / urban planning - which the government is also responsible for. funding the transportation of the victims back to their homes is the least they can do.
