German astronaut Alexander Gerst posted this image Wednesday on Twitter of Gaza and Israel as seen from the International Space Station, saying "My saddest photo yet. From #ISS we can actually see explosions and rockets flying over #Gaza & #Israel."
The weeks-old conflict that began with Israel airstrikes and rockets fired from Gaza has now expanded into an Israel ground invasion on the enclave and claimed the lives of 630 Palestinians, most of whom were civilians and about 30 Israelis, mostly soldiers.
