The British pound recovered Friday from weakness prompted by a Russian decision to expel British diplomats, as the world rallied in support for London in a crisis sparked by the poisoning of a double agent, analysts said.
World stocks, meanwhile, rose slightly at the end of a volatile week as fears lingered of a global trade war, tarnishing a positive economic outlook.
"Yesterday morning the pound fell on headlines that Russia was going to retaliate and expel British diplomats," said Fawad Razaqzada, market analyst at Forex.
The pound then "started to recover" after the leaders of France, Germany and the United States blamed Russia for a nerve agent attack on former spy Sergei Skripal, saying there was "no plausible alternative explanation" for the assault.
"There is nothing like a Russian boogieman to bring EU and UK political adversaries together," wrote Jasper Lawler, head of research at the London Capital Group.

Attention now turns to the Federal Reserve's monetary policy meeting next week. A rate rise is expected but its statement and new bank boss Jerome Powell's comments will be pored over for clues about future hikes with speculation it could announce three more this year.
"It's shaping up to be arguably one of the most critical central bank policy events in some time as Jay Powell gets set to dictate the course of Fed policy for the remainder of 2018 and beyond," said Stephen Innes, head of Asia-Pacific trade at OANDA.
Further uncertainty has been fanned by reports that Trump is planning to sack his National Security Advisor HR McMaster, just days after Secretary of State Rex Tillerson was ousted and not long since Trump's chief economic advisor Gary Cohn resigned.
