"The patrol aircraft identified the Il-20 aircraft of the Russian Air Force over the Baltic Sea near the Latvian border," the agency said.
Other details of the incident are not specified.
Earlier, a Russian warship was discovered not far from the coast of Latvia, in the exclusive economic zone of the country. It is reported by the press service of the National Armed Forces of Latvia on Twitter.
The incident occurred on October 6.
This is not the first such case. A similar incident took place in May, when Russian naval vessels were spotted in the exclusive economic zone of Latvia, close to the territorial waters of the country. In April, the Russian corvette and the tug boat were spotted five nautical miles from the territorial waters of Latvia.
