Chinese online retail giant Alibaba has reported a 45% rise in revenues for its fourth quarter.

Sales hit 17.4bn yuan ($2.8bn, £1.8bn) in the three months to the end of March, with profits up 49% to 5.7bn yuan ($912m; £600m).

Alibaba saw a huge jump in its mobile revenue. Compared with Q4 last year, mobile revenue was up 352% to 5.2bn yuan ($846m, £556m).

The Chinese firm said that figures were boosted by both an increased number of people using mobile devices and spending more when making their purchases.
