Two bomb attacks on Wednesday targeted Egypt’s army in the restive Sinai peninsula

Two bomb attacks on Wednesday targeted Egypt's army in the restive Sinai peninsula, security officials said.
  
"A large explosion" targeted the military intelligence headquarters in Rafah on the border with the Gaza Strip, one official said.
  
Witnesses said the powerful blast shattered the windows of other buildings in the Imam Ali area in Rafah where the military building is located.
  
Minutes later, a second explosion hit an army checkpoint nearby. There were no immediate reports of casualties.

The attacks come just days after an Al-Qaeda inspired group in the peninsula claimed credit for a Cairo bombing that targeted the interior minister last week, pledging more attacks.

The military has poured troops and armor into Sinai against militancy that surged after the army overthrew President Mohammad Mursi on July 3.
