Near the Israel-Gaza border (CNN) -- After eight days of violence along Israel's border with Gaza and nearly 150 deaths -- the vast majority of them Palestinian -- a cease-fire was declared Wednesday.

The cease-fire, announced in a joint news conference in Cairo with U.S. Secretary of State Hillary Clinton and Egyptian Foreign Minister Mohamed Kamel Amr, took effect at 9 p.m. (2 p.m. ET).

Gazans took to the streets, firing their guns into the air in celebration of what they considered to be a victory over Israel's military.

The agreement calls for Israel to halt all acts of aggression on Gaza, including incursions and the targeting of people, according to Egypt's state news agency EGYNews.
