HELSINKI, Aug. 28 (Xinhua) -- Finland reported another airspace violation by a Russian aircraft on Thursday. A Finnish Hornet F18 fighter had been sent to identify the intruder.
Finnish Defence Minister Carl Haglund told the national daily Helsingin Sanomat without elaboration that there is "an element of purposefulness" in this.
Haglund used a partitive form of Finnish word that leaves room also for other reasons.
The violation took place east of Helsinki at around 9 GMT. Haglund said that Finland was now forced to increase surveillance by aircraft. He did not want to speculate about the reasons for the behaviour of Russian aircraft.
It was the third suspected Russian violation of Finnish airspace within a week.
Last Saturday a Russian aircraft was suspected to have violated Finnish air space briefly in west coast.
A second suspected violation was reported on Thursday east of Helsinki. The aircraft was said to be an Antonov AN-72, used for surveillance as well as transportation.
