Rocket fired towards Israel from Lebanon
Lebanese security forces stand guard outside a car showroom where a rocket exploded in Shiah, a southern suburb of Beirut, on May 26, 2013. Hours later another rocket was fired towards Israel.
A rocket was fired from the southern Lebanese town of Marjayoun towards Israel Sunday.
It is unclear if the rocket landed on Israeli territory but local residents report hearing the blast.
"An explosion was heard. Soldiers are searching the area. The cause is still being investigated," an Israeli military spokeswoman said.
The Israeli Defense Forces have begun searching for the rocket's remains.
Earlier Sunday, two rockets were fired towards a Hezbollah-dominated neighborhood in southern Beirut.
The blast injured five people but it was unclear who was being targeted.
On Monday, Lebanese officials, denying witness reports, said a rocket had not been fired from south Lebanon towards Israel, Hezbollah-affiliated Al-Manar website reported.
A senior Lebanese military official said on the 'Voice of Lebanon' radio that "no rocket was fired on Israel."
