Some Hamas officials suggested on Tuesday that Israel carried out the bombing, while other Hamas leaders insinuated the PA did.
Abbas also said that if Hamdallah and Faraj had died in the bombing, a bloody inter-Palestinian conflict would have broken out.
Abbas also said that the Ramallah-based Palestinian leadership does not want any details from the Hamas-run security forces’ investigation into the bombing.
The Hamas-run security forces in Gaza have been investigating the bombing and arrested a number of individuals suspected of carrying it out, according to Hamas-run Interior Ministry spokesman Iyad al-Bozm.
However, the PA president did not explicitly state which measures he decided to take, but he appeared to suggest that they will affect Gazans when implemented.
Last year, Abbas ordered cuts to budgets allocated to Gaza for electricity, medical services, government employees’ salaries and other purposes to pressure Hamas to cede control of the coastal enclave. Many of these cuts remain in place.
