The Lebanese Army has warned neighboring Syria it will respond to any further cross-border attacks, after a Syrian government helicopter fired three missiles that hit the Lebanese border town of Arsal.
Lebanon's army issued the warning on June 12 after the incursion.
It said Lebanese military forces deployed in the Arsal area would "respond immediately to any similar violations."
There were no immediate casualty reports in the June 12 incident.
It's the first such attack from Syria on an urban area inside Lebanon since the beginning of the Syrian conflict in 2011.
In a separate development, Syrian opposition activists said on June 12 that Syrian rebels have killed dozens of Shi'ite Muslim militants in the village of Hatla, in the eastern province of Deir el-Zour.
The Britain-based Syrian Observatory for Human Rights said most of the victims in the June 11 attack were pro-government militiamen.
Government officials said there were children and the elderly among the victims.
Most Syrian rebels are Sunnis.
President Bashar al-Assad belongs to the minority Alawite sect, a Shi'ite offshoot.
