Wall Street rose overnight, with a late burst of buying, on positive jobs data, setting aside news that euro-zone leaders told Greece they won't negotiate a new bailout offer until after the July 5 referendum.
"There were hopes of a deal earlier in the morning and the hopes are literally taken off the table," Adam Sarhan, chief executive of Sarhan Capital in New York, told Reuters.
Fresh talks broke down after Greek Prime Minister Alexis Tsipras told Greek voters to reject an international aid proposal in the upcoming referendum.
"Given the political situation, the rejection of the previous proposals, the referendum which will take place on Sunday, and the recommendation by the Greek government to vote 'no,' we see no grounds for further talks at this point," Eurogroup President Jeroen Dijsselbloem said in a statement after a conference call discussing Tsipras' Tuesday night proposal.
Europe's Stoxx 600 Index ended the day with a 1.5 per cent gain from the previous close. The UK's FTSE 100 Index rose 1.3 per cent, France's CAC 40 Index advanced 1.9 per cent, while Germany's DAX gained 2.2 per cent.
Most of the gains came after reports that Tsipras had sent a letter outlining general acceptance of the current creditors' offer. Gains were pared after Tsipras's address to the nation.
