Story highlights Hezbollah leader: "We will pick time, place and manner" to retaliate against Israel for death of Samir Kuntar

He was killed in an airstrike Sunday in Syria; Israel has declined to comment on accusations it is behind the strike

Kuntar was sentenced to life in prison for killing three Israelis but released in a high-profile 2008 swap

(CNN) Hezbollah leader Hassan Nasrallah on Monday threatened Israel with retaliation after an apparent airstrike killed a senior Lebanese militant a day earlier in Syria.

"It is our right to revenge (Samir Kuntar's) assassination, and we will pick the time, place and manner to do so as we deem appropriate," Nasrallah said in a televised address. "This is our right."

Hezbollah accused Israel of carrying out the airstrike that hit a residential building in the suburbs of Damascus, killing Kuntar. The Israeli military has declined to comment on the accusation.

Samir Kuntar is taken to be processed for release on July 16, 2008, at the Hadarim Prison in central Israel.

Nasrallah's vow for revenge came hours after weapons fire was exchanged along the Israel-Lebanon border.
