The Zionist regime's troops murdered four Palestinian combatants, including two senior commanders, in a raid in the West Bank town of Beit Lahm on Wednesday March 12.

"Islamic Jihad and the other resistance groups have the right to respond in any place to this crime of assassination and all options are open," Dawud Shihab, a spokesman for Islamic Jihad in Gaza, told reporters.

"What the enemy has done undermines any talk of a ceasefire," he said.

"Israel bears full responsibility for the results and the consequences of this war and this escalation."

The martyrs included Mohammed Shahada, 48, a top leader in the armed wing of the Islamic Jihad Movement, and Ahmed al-Balbul, 48, a senior official in the al-Aqsa Martyrs Brigades, an armed group loosely tied to Palestinian President Mahmud Abbas's Fatah Party, Palestinian security officials said.

The other two men were identified as Imad al-Kamel and Eissa Marzuk, both Islamic Jihad combatants.

Earlier in the day, the Zionist regime's troops murdered another Islamic Jihad combatant in a pre-dawn gunbattle in the north of the occupied West Bank, Palestinian medics and witnesses said.

The regime's troops surrounded a house in the village of Saida and demanded that its residents come out, according to Abdel Karim Hammad, whose family lives in the house.

Zionists brought out Saleh Karkur, 27, a member of his family and murdered him, Hammad said.

The usurper Zionist regime's troops then demolished half of the house and abducted Hammad's father, he said.

Palestinian medics said they took the man's body from the scene.
