The leader of the Lebanese militant Hezbollah group has claimed responsibility for launching the drone aircraft that entered Israeli airspace earlier this week.

The rare admission Thursday by Hassan Nasrallah raises regional tensions at a sensitive time when the group's backers, Syria and Iran, are under pressure.

Earlier Thursday, Israeli Prime Minister Benjamin Netanyahu accused Hezbollah of launching the drone.

The unmanned aircraft was shot down by Israel, but the infiltration marked a rare breach of Israel's airspace. Hezbollah had been the leading suspect because of its arsenal of sophisticated Iranian weapons and a history of trying to deploy similar aircraft.
