The UN peacekeeping mission in southern Lebanon has withdrawn unarmed observers from two of its observations posts along the border with Israel, the United Nations said on Friday.
A UN statement did not say how many observers were affected by the shift.
The move left four of the numerous UN patrol bases in the area unoccupied.
UN observers five days earlier had been pulled out of a base at Maroun al-Ras after a peacekeeper was seriously wounded by Hizbullah small arms fire, and a second base was left unmanned after it was destroyed by an Israeli air strike on Tuesday that killed all four observers on duty there.
The four dead were part of the UN truce Supervision Organization, a unit of about 155 observers under the command of the UN interim Force in Lebanon, known as UNIFIL, which has about 1,990 troops in the area.
"All UNIFIL positions in the area of operation remain permanently occupied and maintained by the troops," UNIFIL said in a statement released in Naqoura, Lebanon, and in New York.
