Wow! I am sure your brother is nowhere near that place as it is not a place fit for a honeymoon! Everything seems to be fine now and the authorities are still downplaying the incident, to the point there is no official confirmation it was a mine, although there was undoubtedly an explosion.
I was just reading an article in The Wall Street Journal decrying the fact that Westerners are tired of supporting this war. Once you tell them that other European countries and people may be at risk of becoming collateral damage that certainly would not improve their mood.
Nice to hear from you and congrats to your brother!
