Arafat In June 2011 Dahlan was expelled from Fatah because of repeated claims by Palestinian president Mahmoud Abbas that he had murdered Arafat. In September, his house was raided by the Palestinian police and his private armed guards were arrested. In August 2011 his former party accused him of murdering Arafat using poison. In June 2012, after a 9-month investigation launched by Al Jazeera, traces of the radioactive poison polonium were found on Arafat's belongings, strongly increasing suspicions that he was poisoned. Al-Mabhouh assassination Hamas has claimed that two Palestinians arrested in Dubai for suspected involvement in the assassination of Mahmoud al-Mabhouh, Ahmad Hassanain and Anwar Shheibar, are former members of a death cell which carried out violent suppression of Hamas members, and work at a construction company in Dubai owned by Dahlan.

Others claim that, for the sake of deterring political rivals and counterweighting the numerous armed militias, he maintained a private army in the Gaza Strip in 2003 and 2004, which was trained and equipped by American services, with Israel intending to force a conflict between Dahlan's forces and Hamas.
