Israel launched two air strikes on northern Gaza early Wednesday after Palestinian militants launched a missile at nearby Netivot despite a truce that went into effect on Tuesday, the European Pressphoto Agency reported.

One man was injured when the Grad missile landed in the southern Israeli town Tuesday night, according to The Jerusalem Post. 

Prime Minister Benjamin Netanyahu had cautioned on Tuesday that Israel would respond to any attempts to violate the truce, Reuters reported.

"Our message is that quiet will bring quiet. Anyone who violates it or even tries to violate it, our guns will find him," Netanyahu said in a speech in Jerusalem.

Palestinians carry the body of Islamic Jihad militant Bassam al-Ejla during his funeral in Gaza City on March 13, 2012.

Reuters reports from Gaza — An Egyptian-brokered truce between Israel and militant groups in the Gaza Strip began to take hold on Tuesday after four days of violence in which 25 Palestinians were killed and 200 rockets were fired at Israel.

The number of Palestinian rocket attacks dropped steeply after the ceasefire went into effect overnight. The Israeli military said three rockets had hit, causing no casualties, and that there had been no Israeli air strikes in the Gaza Strip.

Previous ceasefire deals after earlier rounds of fighting have often got off to a slow start, with guns falling silent within a day or two. Read more.
