Sami Abu Zuhri, Hamas movement's spokesman in Gaza, said in an emailed press statement that Hezbollah has the right to respond to the Israeli occupation's assaults and attacks, mainly the last one.
The Lebanese Daily Star website has earlier reported that Hezbollah fighters attacked an Israeli military convoy in the occupied Shebaa Farms, killing four soldiers in a clear response to a recent Israeli airstrike.
The Gaza-based Islamic Jihad's armed wing, al-Quds Brigades, also said in an emailed leaflet that it hails the armed attack on an Israeli army patrol near Shebaa Farms in south Lebanon, Xinhua reported.
The Palestinian Left-wing Popular Front for the Liberation of Palestine (PFLP) also said in an emailed press statement that it welcomes "the heroic armed attack of Hezbollah fighters against the Israeli army."
Spokesman of the pro-Hamas Popular Resistance Committees (PRC) Khaled el-Azbat said in an emailed press statement that his group welcomes the attack in southern Lebanon.
"Any resistance action carried out against the Israeli occupation forces whether in south Lebanon or in any occupied part of the Arab and Palestinian lands, is certainly welcome," he said.
