It has been the worst violence to shake the region since an 11-day war between Israel and Gaza militants last year.
In a statement, the Israeli military said the rocket landed in an open area in northern Israel early Monday, causing no damage or injuries. Shortly after, the military said it struck “the sources of the projectile launched and an infrastructure target in southern Lebanon.” It said “routine activity” in northern Israel was continuing and there were no special precautions being asked of civilians in the area.
There was no immediate claim of responsibility for the rocket fire, but Brig. Gen. Ran Kochav, the military spokesman, told Israeli Army Radio that he assumed the rocket was launched by Palestinian militants in Lebanon spurred on by the recent events in Israel, the West Bank and Gaza.
He said Israel’s response was meant “to make clear to all who are on the other side, whether it is Palestinian factions, Hamas, the government of Lebanon or Hezbollah that we won’t allow Israeli sovereignty to be violated,” he said.
Israel and Lebanon’s militant Hezbollah group are bitter enemies that fought an inconclusive monthlong war in 2006. The border area has remained tense but mostly quiet since then.
Small Palestinian groups are also active in Lebanon and have been suspected in several rocket attacks in recent years.
