According to News.com.au
the two helicopters were part of a fleet of four which were en-route through Kenya to reinforce the African Union mission in Somalia. Only one landed in the northern Kenyan town of Garissa, the other undertook an emergency landing in the Mount Kenya region, its five crew-members have been successfully rescued.
According to the spokesperson of the Ugandan military -- Col. Felix Kulayigye -- the Kenyan Air Force and other authorities in the country have found the two Mi-24 Hind gunships, both helicopters made what he called a "hard landing." He also said there were no fatalities.
These military helicopters were most likely being sent to Somalia to launch an offensive against al-Shabab militants in the Somalian port of Kismayo, where these militants still hold territory.
