A second wave of suicide bombings struck the village of al-Qaa near Lebanon's border with Syria on Monday (June 27th) evening, wounding at least 13 people, AFP reported.
There were four suicide bombings in the latest violence, a military source said.
At least one of them struck near a church, while two bombers detonated their explosives near an armoured personnel carrier and a military intelligence unit.
Two of the attacks were near the municipality building in the village centre.
Five people also were killed and 15 wounded before dawn Monday when four suicide bombers attacked the village.
"Clashes are ongoing on the outskirts of the village between the Lebanese army and armed groups," a security source said.
Al-Qaa Mayor Bashir Matar issued an urgent call to residents to stay indoors in televised remarks, warning more suicide bombers could be roaming the village.
The army has been carrying out searches in the refugee camps, looking for weapons or wanted people, the National News Agency reported Tuesday.
Lebanese army chief General Jean Kahwaji said al-Qaa and other border villages "represent Lebanon's first defence lines against terrorism".
Al-Qaa is one of several border posts separating Lebanon and Syria.
