JERUSALEM, June 4 (Xinhua) -- The Israel Defense Forces (IDF) on Wednesday night issued an urgent warning to residents of the Gaza Strip to avoid moving northward for their safety.

IDF spokesman Avichay Adraee addressed Gazan residents who have returned or intend to return to Beit Lahia, Jabalia, and Beit Hanoun, all north of Gaza City, on social media X, warning that the IDF is operating in these areas with "heavy force."

He stated that the areas north of Salah Khalaf street in Gaza City and Al Quds street in Jabalia are considered dangerous combat zones.

"For your safety, refrain from moving north towards these areas," the warning read.

Israel resumed its assault on Gaza on March 18, following a two-month truce with Hamas. Since then, more than 4,000 Palestinians have been killed, according to Gaza-based health authorities.
