(Changes comment, updates prices) BEIJING, April 27 (Reuters) - London aluminium prices edged lower on Friday after a 1.3 percent jump in the previous session, as traders continued to grapple with the fallout from U.S. sanctions on Russian producer Rusal ahead of a two-day holiday in China. "All of the metals remain within yesterday's ranges as pre-Labour Day weekend positional re-adjustment seems to be the main theme so far today," broker Marex Spectron said in a note. Aluminium has lost about 8.2 percent in London this week, having fallen sharply on Monday and Tuesday after the United States gave American customers of Rusal more time to comply with the sanctions, which were first announced on April 6. This has left it on course for its biggest weekly drop since August 2011, although it is still up 13.1 percent in April on the back of Rusal concerns, which would be its best month since September 2010.
