The Israeli missile warning system will be tested in Kyiv, - Ukrainian Ambassador to Israel Yevhen Korniychuk.
When Russian planes take off, for example, in Belarus, the alarm is activated immediately in all the northern regions of Ukraine.
Israel has powerful radars that calculate exactly where the rocket is flying, and the siren turns on sectorally in a specific place, Korniychuk reports.
In addition, the siren gives a special signal indicating how many minutes the population has to take cover in the shelter, he added.
