Starbucks says its profit rose in its second fiscal quarter as the world's biggest coffee company saw sales increase in the Americas and Asia.

The Seattle-based company, which has more than 18,000 locations around the world, raised its outlook for the year.

Global sales at cafes open at least 13 months rose 6% during the three months ended March 31.

That included a 6% increase in the Americas, its biggest region, where the number of average transactions and spending per visit increased.

In China and the Asia Pacific, where it is looking to grow, the figure rose 8%.

But it fell 2% in Europe, where Starbucks has struggled and has been working to turn around results.

For the quarter, Starbucks earned 390.4 million US dollars (£253m), or 51 cents per share. That is up from 309.9 million US dollars (£200m), or 40 cents per share, a year ago. Not including one-time items, it earned 48 cents per share, in line with analyst estimates.

Revenue rose 11% to 3.56 billion US dollars (£2.30bn). But that was shy of the 3.58 billion US dollars (£2.32bn) Wall Street expected, according to FactSet.

Shares of Starbucks were down 3% in after-market trading.

The company says it now expect full-year earnings of 2.12 to 2.18 US dollars, up from the previous forecast of 2.06 to 2.15 US dollars per share.
