Israel's military launched an overnight raid on Gaza's largest hospital

The largest medical facility in Gaza, Al-Shifa Hospital, was the site of a raid by the Israeli military early Monday morning, with reports of gunshots, a fire breaking out on the complex and, according to the military, at least 20 people killed.

The Israeli military said it was "operating to thwart terrorist activity in the Shifa hospital," and carrying out "precise operational activity" in order to track senior Hamas terrorists allegedly inside the building, where displaced civilians have taken shelter.

"During the activity, terrorists opened fire at the troops from within the hospital. The troops responded with live fire and hits were identified. Our troops are continuing to operate in the area of the hospital," the Israeli military said in a statement.
