Egypt's officials vow to go after the killers of the 16 Egyptian soldiers - 8/5/2012

“There is a red line and passing it is not acceptable. Egyptians will not wait for long to see a reaction to this event,” the Egyptian army said in a statement.

The military claimed the attackers had the help of Palestinian militants, saying “elements from the Gaza Strip” aided them by shelling the Egyptian-Israeli border crossing with mortars as the attack was taking place.

Sunday’s attack was the deadliest on Egyptian soldiers since the country’s last war with Israel nearly 40 years ago.
