A landmine explosion killed five soldiers and injured three others on Saturday in Ukraine in the troubled eastern part of the country.
Alexander Motuzyanik, the presidential administration spokesman for the military operation, spoke regarding the issue on Sunday telling reporters the explosion occurred the previous day close to the village of Donetsky in the Lugansk region along the front line.
Russia and Ukraine have been at loggerheads ever since the ousting of the pro-Russian President Victor Yanukovych in February 2014.
A trend of increasing violence between the Ukrainian central forces and pro-Russian separatists in the eastern part of the country have started to endanger peace and ceasefire measures agreed in Minsk.
Despite the international cease-fire signed in February, fighting still continues along Ukraine's front line.
The United Nations estimates that over 6,000 people have died in the fighting between pro-Russian rebels and the Ukrainian government since it broke out in April 2014.
Kiev views the conflict as a Russian invasion of its territory.
