UPDATE (9 May 2014 at 8:00 a.m. MST):
Due to ongoing uncertainty in Ukraine, 67 missionaries formerly serving in the Ukraine Donetsk Mission who had previously been transferred to other areas within Ukraine will be reassigned to missions within their home countries to complete the remainder of their service. Forty-one missionaries who anticipated serving in Ukraine have been reassigned to other missions.
UPDATE (11 April 2014 at 8:00 a.m. MST):
Due to continued unrest in the region, the Church has chosen to transfer the 85 missionaries from the Ukraine Donetsk Mission to serve in other areas within Ukraine. The wellbeing of missionaries is always our first priority, and every effort is being made to keep them safe.
UPDATE (6 March 2014 at 10:00 p.m. MST):
Given the evolving situation in Ukraine, 22 missionaries serving in that country will end their missions early and return home over the next few days. This includes missionaries originally scheduled for release in March and April of this year and allows the four missions in Ukraine to better accommodate the missionaries who were moved out of the Crimean Peninsula. Missionaries who have been in missionary training centers preparing to enter Ukraine are being temporarily reassigned to other missions or will remain at the MTCs on a short-term basis.
UPDATE (2 March 2014 at 9:00 p.m. MST):
On March 1, 2014, The Church of Jesus Christ of Latter-day Saints reported that due to civil unrest, 23 missionaries serving in the Ukraine Dnepropetrovsk Mission have been removed from the Crimean peninsula and transferred to other areas within the mission as a precautionary measure.
"We are closely watching the situation in Ukraine and communicating regularly with area leadership and mission presidents," said Elder David F. Evans, executive director of the Church's Missionary Department. "Missionary safety is our top concern and mission presidents are providing regular updates to the missionaries' families."
Elder Evans added that circumstances may delay new missionaries from entering Ukraine.
The Kyiv Ukraine Temple remains open to patrons.
