G8 leaders vow to combat financial turmoil

At the end of their two-day summit here, the leaders of the G-8 -- the exclusive group of top eight economic nations made up of the US, Japan, Britain, Germany, France, Italy, Canada and Russia -- agreed that growth and jobs must be their "top priority." 

With Greece's political and economic upheaval high on the summit's agenda and stoking concerns over instability in Spain and Italy, Group of Eight leaders sought to calm the situation.

Obama, who has pressed Europe for more growth-boosting measures like those he pursued at home, used his closing statement to remind euro-zone leaders that the stakes were high and there could be "enormous" costs if they failed.
