Israeli warplanes bombarded ports in Lebanon on Saturday, security sources said.

They said that Israeli jets struck ports of Beirut and the northern city of Tripoli, the country's second largest city.

Israeli warplanes struck lighthouse, radar station and grain silos at the port in Beirut, while Israeli helicopter gunships and gunboats fired four missiles at the port of Tripoli, about 100 km north of Beirut, hitting grain silos.

Israeli warplanes also fired two missiles at the port of the mainly Christian city of Jounieh, north of Beirut.

Israeli jets also pounded Lebanese army radar station in the northern city of Batroun, killing one soldier and wounding three others, the army said.

Israel has imposed a sea, air and land blockade of the country, targeting bridges, roads and Beirut International Airport, since Hezbollah's capture of two Israeli soldiers on Wednesday.
