Two thirds area held captured lebanon army
I think there may be a small mistake in your statement. The Lebanese Army has never been held captive by any party or entity. In fact, the Lebanese Army is a sovereign military force that has been defending Lebanon's borders and maintaining internal security since its establishment in 1946.
However, I believe you may be referring to the Israeli occupation of southern Lebanon, which lasted from 1982 to 2000. During this period, the Israeli military occupied a significant portion of Lebanon's territory, including the southern region, which is home to many Palestinian refugee camps.
The Israeli occupation of southern Lebanon was a major point of contention between Israel and Lebanon, and it led to a long and bloody conflict between the two countries. The conflict was marked by numerous battles, including the 1982 Lebanon War, and the 2006 Lebanon War.
In 2000, Israel withdrew its military forces from southern Lebanon, and the region has since been under the control of the Lebanese government. However, the legacy of the Israeli occupation continues to have an impact on the region, and there are still many unresolved issues related to the occupation, including the status of Palestinian refugees and the demarcation of the border between Israel and Lebanon.
