A lot of pretty big explosions on the ground in Kiev during and after Patriot fired 30+ missiles says:

1. Patriot is not working so well - a lot getting through (Saudi's already know it is a dud, that's why they (and Ukraine) want Israeli missile defence systems that actually work);
2. Looks like at least one Patriot battery destroyed and another damaged (damaged one is what the US is talking about so they are not outright lying).
