"The Israeli enemy strike on Baalshmay killed five people," the health ministry said in an initial report.

The security official, speaking anonymously due to the sensitivity of the matter, said the "Israeli strike targeted a house where displaced people lived, including women and children".

Israeli strikes have often targeted buildings where displaced civilians have sought refuge.

On Monday, Israel struck Lebanon's northernmost Akkar region, killing at least eight people according to the ministry, in one of the farthest attacks from the Israeli border since war erupted in September.

On Sunday, Lebanon said an Israeli strike killed 23 people, including seven children, in the village of Almat, north of the capital.

On Tuesday morning, Israel launched more than a dozen air strikes on south Beirut, state media said.

"Israeli warplanes launched a violent strike targeting the Hadi Nasrallah highway, which is the 13th raid on Beirut's southern suburb," the state-run National News Agency said.

The NNA also reported Israeli strikes in the eastern city of Hermel and the southern city of Nabatiyeh.

Last month, Israeli strikes razed Nabatiyeh's historic marketplace, with another wave of attacks hitting city hall and killing several people including the mayor.

Since September 23, Israel has stepped up its bombing campaign in Lebanon. A week later, it sent ground troops into Lebanon.

More than 3,240 people have been killed in Lebanon since the clashes began last year, according to the health ministry, the majority of them since late September.
