By Michael Holden LONDON (Reuters) - Britain held a minute of silence on Tuesday to mark the 10th anniversary of al Qaeda-inspired attacks in which four suicide bombers killed 52 people across London's transport system. The commemoration came just four days after the country came to a standstill to mourn a massacre of mainly British tourists at a resort in Tunisia last month. The government and security services warned the threat of further attacks remains severe.
By Paul Taylor and Renee Maltezou BRUSSELS (Reuters) - Greek Prime Minister Alexis Tsipras launched a desperate bid to win fresh aid from skeptical creditors at an emergency euro zone summit on Tuesday, before his country's banks run out of money. With Greek banks down to their last few days of cash and the European Central Bank tightening the noose on their funding, Tsipras tried to convince the bloc's other 18 leaders, many of whom are exasperated with five years of crisis, to authorize a new loan swiftly. Merkel, under pressure in Germany to cut Greece loose, made clear it was up to Tsipras to present convincing proposals after Athens spurned tax rises, spending cuts and pension and labor reforms that were on the table before its 240 billion euro ($262.7 billion) bailout expired last week.
