Hezbollah fighters attacked an Israeli military convoy in the Shaba'a Farms border area Jan. 28, killing four soldiers. After Israeli forces were hit by missile fire, they responded by firing shells into southern Lebanon. A Spanish UN peacekeeper was accidentally killed by the Israeli return fire. Hezbollah issued a communiqué saying the attack was retaliation for an Israeli air-strike that killed six of its fighters and an Iranian Revolutionary Guards general on the Syrian-held side of the Golan Heights 10 days ago. Hezbollah said the attack had been carried out by a cell calling itself the "Heroic Martyrs of Quneitra," a reference to the area where the Israeli strike took place on Jan. 18.

Shaba'a Farms is a small area occupied by Israel adjacent to the Golan Heights. Hezbollah claims the Farms are part of Lebanon, and uses this claim to justify its continued armed resistance, and  confrontational posture towards Israel. The UN believes the area is part of the Golan Heights and therefore legally part of Syria.
