* 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.
* GLENCORE XSTRATA : Glencore Xstrata has sold its interest in the Las Bambas copper mine in Peru to a Chinese consortium in a $6 billion cash deal, making it one of China's largest mining acquisitions in recent years.

* BANKS: Europe's largest banks cut their staff by another 3.5 percent last year and the prospect of a return to pre-crisis employment levels seems far off, despite the region's fledgling economic recovery.
Separately, the European Union will sign off on a slew of major reforms this week to allow failing banks to be wound down without public money, clearing its desk before elections in May that may lead to a slower pace of legislation.
Also, British investors have called upon investment banks to stick closer to lock-up agreements on sales of company shares after a major transaction, saying it would ensure more stable markets.
