Israel's military intelligence chief says Gaza militants have successfully tested an Iranian rocket able to reach metropolitan Tel Aviv.

Israeli radio stations say Maj. Gen. Amos Yadlin told lawmakers Tuesday that the rocket could fly 37 miles. That would put Israel's largest urban center at risk.

Until now, rockets fired from Gaza have reached up to 25 miles, putting one-eighth of Israel's population within rocket range.

Israel launched a bruising war against Gaza militants last winter to quash years of rocket fire.

Although the rocket fire has decreased dramatically, Israeli officials say weapons continue to reach militants through tunnels under Gaza's border with Egypt.
