Hezbollah said Saturday its fighters clashed with Israeli troops who infiltrated a town in eastern Lebanon overnight, as Lebanese authorities reported at least 16 people killed in Israeli strikes on the area.

In a statement, Hezbollah said its fighters had "observed the infiltration of four Israeli enemy army helicopters from the Syrian direction".

After landing and disembarking, the advancing troops "were engaged" by a group of Hezbollah fighters as they reached a cemetery in the town of Nabi Sheet, Hezbollah said.

"The clash escalated after the enemy force was exposed," it added, saying the Israeli troops launched intense strikes before evacuating

There was no immediate comment from the Israeli military.
