Today, we will remember them and we will honour them.
Nat, disappointing news from overseas, in the Ukraine.
It's been announced by the Dutch prime minister that the search has been suspended for the remains of those who have yet to be found and identified.
It's been suspended for an indefinite amount of time due to rising tensions between Kiev and the pro-Russian separatists.
So hopefully that will not be a long delay in that search to recover the missing bodies will be able to resume as soon as possible.
That's not good news.
