An Egyptian militant group has claimed responsibility for twin suicide bombings that killed three people and wounded eight on Friday in the southern Sinai Peninsula.

In a statement posted Sunday on militant websites, al-Qaida inspired group Ansar Beit Al-Maqdis warned the Egyptian army "we will not rest until we achieve retribution for the blood and honor of the Muslims."

In the first attack, a suicide bomber blew himself up in front of a bus carrying workers, killing one and wounding three. Another bomber blew himself up at an army checkpoint, killing a soldier and a civilian passer-by and wounding five others.

The group urged the Egyptian people to "rebel against this oppressive and tyrannical regime" and not resort only to peaceful opposition movements.
