The reporter and a second cameraman had to crawl through fields for two hours until they were rescued by residents of Wadi Khaled, Wehbe said.
Al-Jadeed is traditionally supportive of the regime of Syria's President Bashar al-Assad. But Wehbe said the network blames the Syrian military for the attack "because that area is under the full control of the Syrian military."
Lebanese Prime Minister Najib Mikati tweeted that the incident will be investigated, and said Lebanon deplores and condemns the shooting from the Syrian side of the border. Lebanon will inform Syria of its condemnation, demanding that perpetrators are held to account, Mikati said.
The New York-based Committee to Protect Journalists similarly denounced the attack, saying the situation "is taking yet another dangerous turn as the violence spills beyond Syria's borders, and journalists working in neighboring nations are placed at risk."
SANA said the incident at the Lebanese border took place "when the Syrian border checkpoint came under heavy gunfire from terrorist armed groups." Throughout the more than year-long uprising, Syria has routinely blamed violence on such groups.
A checkpoint came under attack by terrorists who were trying to infiltrate Syria, SANA reported. The report also expressed condolences to the cameraman's family and colleagues, and to Al-Jadeed.
Inside Syria, deaths were reported Monday in Hama, Idlib, Deir Ezzor, Homs, Daraa, and Aleppo, according to the LCC.
The latest violence came a day after Syrian Foreign Ministry spokesman Jihad Makdissi announced that suggestions Syria had agreed to withdraw its troops from cities on April 10 were "a wrong interpretation," according to SANA.
The regime will not commit to pulling out forces only to have "armed terrorist groups" attack, he said.
Early last week, diplomatic officials said the Syrian government agreed to an April 10 deadline to withdraw troops from cities. The agreement came after Syria said it accepted a peace plan laid out by U.N.-Arab League special envoy Kofi Annan. The envoy is expected to be in Turkey on Tuesday, according to the country's Anadolu news agency.
Makdissi said Damascus has acted in "good faith." And he complained that Annan "has not offered written guarantees to the Syrian government that the armed groups agreed to stop violence, nor has he offered guarantees that Qatar, Saudi Arabia and Turkey will commit to stop funding and arming terrorist groups." Those governments have denied such accusations from Syria.
Rebels, including defectors from al-Assad's forces, have taken up arms, but their strength has often paled in comparison with the better-equipped regime troops.
"We can't drop our guns until the regime withdraws from the cities," Lt. Abdullah Odah of the rebel Free Syrian Army said from Istanbul. "We didn't start the mass murder. The regime started it. It has to stop killing, and then automatically we will stop."
U.S. Sen. John McCain was in Turkey on Monday and met with various opposition leaders, who the veteran senator described as "a group of patriots who need our help as Syrians are being massacred."
Amid the conflict, human rights groups have worked to detail what they describe as horrors being carried out by al-Assad's regime.
The new Human Rights Watch report documents "more than a dozen incidents (of executions) involving at least 101 victims since late 2011, many of them in March 2012," the group said.
"In a desperate attempt to crush the uprising, Syrian forces have executed people in cold blood, civilians and opposition fighters alike," said Ole Solvang, emergencies researcher for the human rights group. "They are doing it in broad daylight and in front of witnesses, evidently not concerned about any accountability for their crimes."
The Syrian government has consistently blamed violence in the country on "armed terrorist groups." But the U.N. and world leaders have said the government is lethally cracking down on dissidents seeking true democracy and an ouster of al-Assad, whose family has ruled Syria for 42 years.
Opposition activists and U.N. Secretary-General Ban Ki-moon's office have accused the Syrian regime of ramping up violence in the days leading up to the withdrawal deadline.
"The timeline for the complete cessation of violence endorsed by the Security Council must be respected by all without condition," a spokesman for Ban said Monday.
