On February 25, 1994, a Zionist terrorist settler wearing a military uniform, Baruch Goldstein, entered Al-Ebrahimi mosque and shot at the worshippers. After  the massacre in the mosque, the occupation army shot at ambulances and killed and injured dozens of Palestinians. At least 48 were killed and more than 300 were injured. 

This massacre had a big impact on the Palestinian resistance against occupation forces. The operations against the occupation forces before were throwing stones or attacks by knives or armed ambushes against soldiers. After the massacre, the resistance started to carry out large scale operations, including martyrdom operations.

In a statement declared by Ezzdeen Al-Qassam Brigades, Al-Qassam leadership decided to respond to this massacre in five stages. Every stage will give the occupation settlers a bitter lesson about targeting Palestinian civilians.

The one who was very suitable to help in these operations was Thaher Rebhi Kabha. The first operation was done by the martyr Ammar Amarna who put a bag full of TNT in the bus holding a big number of soldiers. The operation resulted in killing at least five and injuring 32 others, including 18 soldiers to prove that the first explosion was targeted a bus full of soldiers not only civilians. 

Thaher was born in city of Jenin in the northern West Bank in  1969. He has seven brothers and sisters. He finished his secondary school from "Ezzedeen Al-Qassam" school in Jenin and studied Islamic studies in the city if Qalqilya.

Thaher was well-known for his good morals and conservative way of life. The matter which prepared him to be a choice of Ezzedeen Al-Qassam Brigades in the field of resistance.
