6 soldiers have been killed in Ukraine following attacks by rebel groups, Al Jazeera reports.
Reports say 4 soldiers died on Sunday when their vehicle was hit by a shell fired by the Russian-backed rebels as it drove across a bridge in the government-held town of Schastye.
Also, in a separate incident less than an hour later, a landmine exploded under a military vehicle at Shyrokyne killing 2 soldiers and injuring a third.
These new casualties in addition to the death of 3 servicemen in a landmine explosion on Saturday, further strains the tenuous ceasefire struck two months ago in the Belarusian capital Minsk.
The Ukranian conflict erupted a year ago when rebels opposed to a new pro-Western leadership in Kiev and the ousting of a Moscow-backed president occupied state buildings in two big cities of Ukraine's Russian-speaking east, Donetsk and Luhansk.
It has since claimed the lives of over 6,000 civilians and service men.
