An explosion of the bomb in the biggest airport of the biggest world's country killed 35 and wounded 152 people. Huge sorrow for the relatives of that people. As Ukrainians say "Вічная пам'ять"(eternal memory) for these people.
That bombing attack shows Russia has not only the biggest territory, but has also very much big problems inside its state. And Ukraine must be aware of such state's neighbourhood and must do all possible to protect itself.
