Unknown gunmen fired heavy- and medium-caliber weapons Tuesday from the Ras al-Ain area towards Baalbek in connection with Sunday's deadly shooting in the northeastern city, state-run National News Agency reported.
The shelling was targeted at “the house of the father of Nader Yaghi,” where the latter's funeral was being held after he was killed in Sunday's incident.
“Lebanese army troops intervened immediately and started pursuing the shooters,” NNA said.
