LONDON, July 10 (Reuters) - European equities fell on Friday and headed for a fourth straight week of losses as worries about corporate earnings and the pace of economic recovery pressured banks, while weaker commodity prices hit oil and mining shares.

By 1114 GMT, the FTSEurofirst 300 index of top European shares was down 0.8 percent at 816.87 points after gaining 0.8 percent in the previous session. It has fallen 3 percent this week, but is still up 26 percent after a record low in early March.

Financial stocks were among the top losers on the index, with Allied Irish Banks (ALBK.I: Quote, Profile, Research), Bank of Ireland (BKIR.I: Quote, Profile, Research), Swedbank (SWEDa.ST: Quote, Profile, Research), HSBC (HSBA.L: Quote, Profile, Research) and UniCreidt (CRDI.MI: Quote, Profile, Research) down 1.8 to 13.3 percent.

Commerzbank (CBKG.DE: Quote, Profile, Research) was flat after gaining earlier. It saw losses narrow in the second quarter versus the first as business with medium-sized companies and retail clients achieved good results, said Markus Beumer, a board member of the bank. [ID:nLA514052]
