KYIV, Ukraine -- Ukraine's parliament has approved Arseniy Yatsenyuk as the country's new prime minister.

The vote was held today amid the sharp rise in tensions in the southern Crimea region, where gunmen seized local government buildings and raised a Russian flag.

The 39-year-old Yatsenyuk has previously served as the economy minister and foreign minister, and a Speaker of parliament.

He was approved by 371 votes in the 450-member parliament.
