Sheikh Hassan Nasrallah on Friday criticized Arab leaders for failing to act quickly to stop the Israeli offensive against the Hamas-controlled Gaza Strip.
Nasrallah said a decision by Arab foreign ministers this week to take the Gaza issue to the UN Security Council next Monday is meant to give Israel more time to smash Hamas.
Nasrallah was speaking from a secret location to a rally south of Beirut Friday night. His comments were also televised.
The Gaza offensive, which is aimed at silencing Hamas rockets, has killed more than 400 Palestinians and stirred up anger across the Arab world.
