There were two attacks at police checkpoints in Gaza on Tuesday.
Two Palestinian policemen were killed in an explosion at a checkpoint near the Al-Dahdouh junction in Gaza City, Palestinian police spokesman Iyad Al-Bazam said.
Al-Bazam said that another explosion targeted a police checkpoint on the Al-Rasheed coastal road in Al-Sheikh Ajleen area, west of Gaza City, leaving a number of injuries.
He said that the police forces and security services are continuing to investigate the sites of the blasts.
A state of alert was declared to all security and police services.
According to the Palestinian Ministry of Health, the "martyrs" in the first explosion were Majid Nadeem, 32, and Alaa Ziad Gerabel, also 32. Two other men and a woman were injured.
Looks like Hamas has some internal enemies who are willing to kill.
