Israel takes 'Hezbollah fighters'
The Israeli army says it has seized a number of Hezbollah fighters in a raid on Baalbek, a town deep inside Lebanon.
After air strikes on the town, 100km into Lebanon, in which 11 people died, Israeli commandos landed by helicopter and fought a lengthy gun battle.
In a statement on al-Manar television, Hezbollah said those captured in Baalbek, one of its strongholds, were "ordinary citizens", not militants.
Israeli troops have also pushed further into south Lebanon overnight.
The incursion into Baalbek began before midnight with several air strikes.
At least 11 civilians, including five members of the same family, were killed in the bombing.
After the bombardment, military helicopters then landed an Israeli commando unit near a hospital on the outskirts of the town, which led to fierce clashes with Hezbollah guerrillas lasting several hours.
Local residents told AP the hospital was run by people close to Hezbollah and funded by an Iranian charity.
The Israeli military says that it seized at least three Hezbollah members in the raid and a spokeswoman told Reuters news agency that the captured militants had been taken to Israel.
Hezbollah say they inflicted casualties on the commando unit but a spokeswoman for the Israeli military says all their troops returned safely to base.
Baalbek, which is a Hezbollah stronghold and home to several senior members of the group, has been repeatedly bombed by Israel since the conflict began.
The BBC's Martin Asser - who visited Baalbek a day before the raids - said the mainly Shia Muslim town was very tense, with many families having fled.
This is the first time Israel has sent ground troops so far into Lebanon since its offensive began over three weeks ago.
The BBC's Michael Buchanan in Beirut says that there had been a slight mood of optimism in Lebanon that diplomatic efforts to bring about a ceasefire following the deadly air strike on the Lebanese village of Qana, in which 54 civilians died, were gathering momentum.
Following this raid, that mood has disappeared, our correspondent says.
Meanwhile, Israeli planes attacked a Lebanese army base south-east of Sidon early on Wednesday, killing three Lebanese soldiers.
A 48-hour partial suspension of Israeli air strikes, triggered by the raid on Qana, ended overnight.
