Jerusalem - Israeli Defence Minister Moshe Yaalon says the military will not sit back while Palestinian militants attack southern Israel from Gaza.
Yaalon's remarks on Wednesday came as two new rockets from the coastal territory exploded at an Israeli border town without injuries, according to police.
"We will not in any way allow a routine of rocket fire steadily dripping on our civilians and soldiers," Yaalon said in a statement.
Hours earlier, Israel struck targets in Gaza in response to Palestinian rocket attacks. It was the first time Israel retaliated for Gaza rocket fire since an informal cease-fire ended eight days of cross-border fighting between Israel and the Hamas-ruled territory in November.
Palestinians in Gaza have fired several rockets since an informal cease-fire took hold after the fighting. One hit Israel on Tuesday.
