Kazakhstan's President Nursultan Nazarbayev has been sworn-in for another seven-year term, after a landslide election victory last month.

The elaborate ceremony took place Wednesday at the presidential palace in the capital, Astana. Mr. Nazarbayev read his oath of office and kissed a light-blue national flag, as hundreds of dignitaries looked on. Among those attending were Russian President Vladimir Putin, Ukrainian President Viktor Yushchenko and Georgian President Mikhail Saakashvili.

The 65-year-old Mr. Nazarbayev has ruled the former Soviet republic for the past 15 years. During that time, Kazakhstan has enjoyed steady economic growth and has become a rising oil power.

Mr. Nazarbayev won re-election December fourth with 91 percent of the vote. But Western observers said the poll was flawed because of tampering with ballot boxes and intimidation of the opposition.
