The Cradle online news magazine reported the development, citing a Tuesday statement by the group in question, which it identified as the Tulkarm Brigade.
An umbrella organization of Resistance forces with different political affiliations, the brigade hails from the city of Tulkarm in northwestern West Bank.
"We announce the start of an expanded operation for all brigades and groups from now until further notice," the statement said.
The announcement came a day after Israeli forces assassinated three Palestinian young men in a violent raid on a Tulkarm suburb.
After targeting the victims, the invading Israeli forces prevented the Red Crescent staff from reaching the area by pointing their guns at the organization's vehicles.
Earlier on Tuesday, Palestinian Resistance forces engaged in intense clashes with Israeli troops in Tulkarm as part of the retaliatory operation that has been announced by Tulkarm Brigade.
The clashes erupted near the Nour Shams and Tulkarm refugee camps in the city when the Israeli military stormed the city at midnight on Monday following the triple assassinations.
During the confrontation, Resistance forces prevented Israeli forces from fully entering either camp.
"[Our] strikes against the enemy forces continue," Tulkarm Brigade added through the Tuesday statement.
The occupying regime has escalated its violent raids across the West Bank since October 7 when it started a brutal military onslaught against the Gaza Strip.
Nearly 340 Palestinians have been killed across the occupied territory as a result of the escalation.
On the other hand, the regime's genocidal war on the besieged Gaza has so far killed around 23,200 Palestinians, most of them women and children, while leaving nearly 59,000 others injured.
