There have been almost non-stop sirens and alerts in Jerusalem since early this morning, punctuated by multiple loud explosions as interceptors strike Iranian missiles passing over the city on their way to targets in central Israel, international correspondent Jason Burke of The Guardian reports.

Israeli paramedic services say about 120 have been injured across the country, though few seriously.

Many residents of Jerusalem spent much of the night in bomb shelters, where available. Streets are largely empty with schools and businesses closed.
