Oct 10 (Reuters) - UK's blue-chip stock index fell for a fourth consecutive session on Monday, amid a wider risk-off sentiment after Russia bombed cities across Ukraine.
The FTSE 100 index fell 0.8% and the mid-cap FTSE 250 index dropped 1% to touch one-week lows, extending Friday's losses, also coming under pressure as strong U.S. jobs data doused hopes the Federal Reserve would temper rate hikes.
Massive explosions shook the Ukrainian capital and other cities during rush hour on Monday morning in apparent revenge strikes by Russia after President Vladimir Putin declared an explosion on the bridge to Crimea to be a terrorist attack.

Mining and oil giants also dropped as commodity prices came under pressure.
British power companies Centrica and Drax fell more than 4% each after the Financial Times reported the UK government was pressing ahead with plans to cap revenues of renewable electricity generators.
