Three people have been sentenced to death for killing Hamas leader Mazen Faqha.
The three men - main suspect Ashraf Abu Leila and two accomplices, identified as Hisham A and Aballah N - were convicted of collaborating with Israel to carry out the killing at Faqha's home on March 24.
It had previously been reported that Leila, a 38-year-old Palestinian Arab, admitted to carrying out the murder, and to collaborating with Israel. His accomplices reportedly helped him by observing and photographing the area.
The court in Gaza sentenced Leila and Hisham to hang, while Abdallah will face the firing squad.
Faqah, a convicted terrorist freed in 2011, was shot four times in the head with a silenced gun after the assailants entered his property. Hamas immediately accused Israel and its 'collaborators' of perpetrating the murder.
Israel has not confirmed or denied the accusations.
