The United Nations Interim Force in Lebanon said late Monday evening that it was in touch with the Lebanese army and was checking the background behind an explosion in the home of a senior Hizbullah member a few hours earlier.

According to one report, the senior Hizbullah member, Abd Al-Nasr Issa, was killed along with his son and as many as three others in the blast. Hizbullah denies that anyone was killed and says one person was seriously injured in the explosion.
