The Israeli military has ordered the evacuation of part of an area in the Gaza Strip it has designated a humanitarian zone. The military said Monday it is planning to begin an operation against Hamas militants who have embedded themselves in the area and used it to launch rockets toward Israel. The area includes the eastern part of the Muwasi humanitarian zone, which is located in the southern Gaza Strip. Earlier this month, Israel said it estimates at least a million Palestinians are now in the humanitarian zone it declared. The zone covers a stretch of about 8.6 miles along the Mediterranean.
