The station said the accused, Bahaeddine Mahmoud Hujeir, is also involved in plotting for the assassination of Lebanese politicians and businessmen.

The Lebanese Army Intelligence had arrested Hujeir last week in the southern Palestinian refugee camp of Ain el-Hilweh.

Hujeir has ties to the ISIS Abdullah Azzam Brigades and to the two suicide bombers who carried out the embassy bombing.

He had prior knowledge of the attackers’ intention and has recently pledged allegiance to the Daesh terror group, it added.

In November 2013, at least 23 people were killed and more than 145 others were wounded in twin blasts near the Iranian Embassy in the neighborhood of Bir Hassan in Beirut's southern suburbs.
