The IDF announced a short time ago (Monday) that large IDF, Border Guard, and Shin Bet forces were entering the city of Tulkarm, with the aim of rooting out "terrorist infrastructures."
This operation follows an almost two week long operation in Jenin which eliminated multiple terrorists and seized and destroyed multiple weapons and explosive devices.
The IDF has recently increasingly focused on anti-terror operations in Judea and Samaria, as reported efforts by Iran to massively arm terrorists in the area for attacks in Israel and against Jewish settlements have ramped up.
Hamas leader Yahya Sinwar in particular is reported to want a "regional war" where Israel is forced to fight both in Judea and Samaria and against Hezbollah, relieving pressure on Hamas forces in Gaza and weakening Israel more generally.
