CAIRO, June 26 (Xinhua) -- At least seven Egyptian policemen, including one officer, were killed in a terrorist attack on different check points in the North Sinai city of Arish, said a statement of the country's Interior Ministry on Wednesday.
"Four terrorists have been killed, including a suicide bomber who set off his explosives at one of the checkpoints attacked," the statement said.
The statement added that the security forces have frustrated terrorist attacks that took place in southern and western Arish on Tuesday night.
The attacks targeted three check points, according to the statement.
Some explosive devices, automatic weapons, hand-made bombs were seized, it added.
No group has claimed responsibility for the attacks yet.
Egypt's government has been battling Islamist militants centered in northern Sinai since the military ousted the Islamist leader Mohamed Morsi, who died last week after collapsing in court, in response to mass protests against his rule in 2013.
Some Islamist groups, including the Sinai-based Islamic State, that claimed most of the previous attacks, pledged revenge for his death.
