"We have crossed into Somalia in pursuit of the Shehab, who are responsible for the kidnappings and attacks on our country," government spokesman Alfred Matua told AFP.
An AFP reporter close to the border witnessed large numbers of troops, as well as military planes and helicopters overhead.
Several witnesses reported heavy troop movement in Kenya`s border regions, with truckloads of soldiers heading towards the frontier.
The assault comes a day after Kenya`s Internal Security Minister George Saitoti branded Somalia`s Al-Qaeda-inspired Shebab rebels "the enemy" and vowed to attack them "wherever they will be".
"Kenya is providing logistical and moral support," said Abdirahman Omar Osman, a spokesman for Somalia`s Western-backed government, which controls the capital Mogadishu with the help of over 9,000 African Union troops.
However, he said it was Somali forces in the south of the country that were "battling the Shebab on the ground".
In just over a month, a British woman and a French woman have been abducted from beach resorts in two separate incidents, dealing a major blow to Kenya`s tourism industry.
On Thursday, two female Spanish aid workers were seized by gunmen from Kenya`s crowded Dadaab refugee camp, the world`s largest with some 450,000 mainly Somali refugees. (*)
