Israeli troops backed by tanks and heavy artillery have stormed the besieged Kamal Adwan Hospital in the northern Gaza Strip, where 3,000 displaced people are sheltering from Israeli’s unrelenting assault. Al Jazeera reports medical staff inside the hospital were among those shot and killed, as were two mothers killed Monday when Israel’s military bombarded the hospital’s maternity ward. The hospital’s remaining patients include a dozen children in an intensive care unit and six newborns in incubators.
