The Lebanese Army Monday apprehended a man suspected of having a role in one of the rocket attacks on Israel earlier this month, a security source told The Daily Star.
The Lebanese man, identified as Ziad Affara from Sidon, is suspected of having assisted Hussein Atwe in firing two rockets from the Khreibeh area in the Arkoub region.
Last week, the Army arrested Atwe, who belongs to Al-Jamaa al-Islamiya and confessed to firing rockets at Israel from the Hasbaya village of Mari earlier this month.
Atwe has reportedly said that his move was in retaliation for Israel's aggression on Gaza.
Unidentified militants have launched salvoes of rockets from Lebanese territory toward Israel on several occasions last week, prompting Israeli retaliatory shelling of Lebanese villages.
The Army has also arrested two Palestinians for transporting rockets to the launch site on July 13 and 14.
The incidents have raised tensions along the Lebanese-Israeli border, which has been relatively calm since 2006. The Amy, Israel and U.N. Interim Force in Lebanon have beefed up their presence along the frontier to prevent possible escalations.
