Hamas terrorists in Kalkilya built a large supply of bombs and stored them in a local mosque without raising suspicion from local Palestinian Authority armed forces who represent the rival Fatah faction. However, the terrorists were out of luck on Wednesday, Passover eve, when a simple electric shortage gave away their plans. The shortage caused a small fire in the mosque, bringing PA forces to the building, where they found bombs ready for use and large cannisters of bomb-making materials. The mosque was closed down, and PA sappers removed the explosives.
