Israeli air strikes have killed at least 13 Palestinians including two boys, a pregnant woman, and nine police officers in war-torn Gaza. An attack on Sunday hit a house in the urban refugee camp of Nuseirat in central Gaza, killing four people, including a couple in their 30s and their 10-year-old son, according to the nearby Al-Aqsa Hospital. The Israeli military body overseeing civilian affairs in the occupied Palestinian territory, COGAT, said the crossing would resume operations on March 18 for limited passenger movement in both directions, with no cargo permitted. The announcement comes as more than 20,000 sick and wounded Palestinians, among them roughly 4,000 cancer patients and 4,500 children, remain on waiting lists for medical treatment unavailable in Gaza. Israel shut the crossing on February 28, the same day it and the United States launched strikes on Iran, citing “security” reasons. The World Health Organization’s regional director for the Eastern Mediterranean warned this week that only about 200 trucks a day were entering Gaza, far short of the estimated daily requirement of 600.
