Monday's attack targeting the policemen took place near the border town of Rafah in northern Sinai. A few hours later, militants shot to death a senior police officer as he stood guard outside a bank in el-Arish, another city in the largely lawless area, security officials said.
There was no immediate claim of responsibility for either attack. The United States condemned the slaying of the police officers and repeated its commitment to help Egypt combat terrorism in Sinai. U.N. Secretary-General Ban Ki-moon also denounced the attack.
The Sinai attack came a day after security forces killed 36 detainees during a riot on a prison-bound truck convoy north of Cairo. The killings came as police fired tear gas to free a guard who was trapped in the melee, security officials said.
Elsewhere, an Egyptian journalist working for a state-run daily was shot dead early Tuesday by soldiers at a military checkpoint, security officials said. Tamer Abdel-Raouf from Al-Ahram and a colleague were on the road after finishing a late-night interview with the recently appointed governor of Beheira province.
They were stopped at a checkpoint, asked for identification papers and told they had broken the dusk-to-dawn curfew. The two then drove off without permission and a soldier from the checkpoint opened fire, killing Abdel-Raouf. His colleague was injured when their car hit a tree, said the officials, speaking on condition of anonymity in line with regulations.
