* The FTSE 100 index fell 80.27 points, or 1.2 percent, to 6,561.70 points on Friday, with technology stocks among the hardest hit as the UK's benchmark equity index suffered its biggest weekly loss in a month with a 2 percent drop.
That leaves the index, which got close to its best level since early 2000 in January, down about 2.8 percent this year.
* U.S. stocks sank on Friday, with the biotech and other momentum stocks again dragging the Nasdaq Composite down 1.3 percent, to close at 3,999.734, falling below the 4,000 mark for the first time since early February.
* Ukraine gave pro-Russian separatists a Monday morning deadline to disarm or face a "full-scale anti-terrorist operation" by its armed forces, raising the risk of a military confrontation with Russia, while the United Nations Security Council held an emergency session on Sunday night to discuss the crisis.
