CAIRO, Jan. 9 (Xinhua) -- At least four policemen were killed and 10 others wounded in an attack outside a police building in Egypt's North Sinai city of al-Arish on Monday, a security source told Xinhua.
A suicide bomber detonated a stolen, explosive-laden garbage truck outside the building, the source added, adding that some floors of the structure have been destroyed in the blast.
The wounded, including two civilians, have been transferred to Arish Public Hospital.
There was no immediate claim of responsibility for the attack.
Bomb attacks are endemic in North Sinai Province, where an Islamic State-affiliated group claims responsibility for most of them.
