JERUSALEM ( CNN ) -- Palestinian militants fired a long-range rocket from Gaza into southwestern Israel on Tuesday morning . It was the first such attack into the city of Ashkelon since the two sides declared a cease-fire , the Israeli military said . This aerial view shows the power station and industrial zone of Ashkelon , Israel , in March of 2008 . The missile fired from a Grad rocket launcher did not cause any injuries or damage in the coastal city , said a spokesman for the Israel Defense Forces . Rockets fired from a Grad have a longer range than the crude , home-made Qassams that Palestinian militants in Gaza fire more frequently . Militants have used Grads to strike farther into Israel . Ashkelon lies 12 miles ( 19 km ) north of Gaza . Israel and Hamas , the Islamic militant group that has ruled Gaza since 2007 , declared separate , tentative cease-fires two weeks ago after more than three weeks of fighting in Gaza . Israel launched the attack on Hamas in Gaza on December 27 with the stated aim of ending rocket attacks on southern Israel . More than 1,300 Palestinians died and about 5,400 others were wounded . Thirteen Israelis , including 10 soldiers , were also killed in the fighting . Since the two sides declared a cease-fire on January 21 , militants have sporadically fired rockets into Israel . Israel has responded with air strikes . CNN 's Igor Krotov contributed to this report .
