Gunmen shot dead a senior Hezbollah commander outside his home on Wednesday in southern Beirut, an attack that the Iranian-backed group quickly blamed on arch-enemy Israel. Israeli officials denied any involvement.

An official close to Hezbollah said Hassan al-Laqis held some of the group’s most sensitive portfolios and was close to the group’s leader, Sheikh Hassan Nasrallah.

Sunni militant groups have claimed responsibility for those attacks, calling it retaliation for Hezbollah’s involvement in Syria.

“The brother martyr Hassan al-Laqis spent his youth and all his life in this honourable resistance since its inception up until the last moments of his life,” the statement said.

A Lebanese security official and the official close to Hezbollah said assailants shot Al-Laqis with a pistol equipped with a silencer at close range after he parked his car in the parking garage on the ground floor of the residential building where he lived in the Hadath neighbourhood, some 3 km southwest of Beirut.

Footage from the scene broadcast on Hezbollah’s al-Manar television station showed the parking lot stained with muddied footprints that led to a nearby small olive grove. Yellow police tape blocked off the area.

Al-Laqis was rushed to a nearby hospital but died early Wednesday from his wounds, the officials said.

The Lebanese state news agency later published a photograph it identified as al-Laqis. The image showed a man who appeared to be in his mid-40s, with neatly cut black hair and a graying close-cropped beard, wearing beige-and-khaki military clothing.

The Hezbollah statement accused Israel of being responsible for the killing. It said Israel tried to kill him several times, but had failed.

“The Israeli enemy is naturally directly to blame,” the statement said. “This enemy must shoulder complete responsibility and repercussions for this ugly crime and its repeated targeting of leaders and cadres of the resistance.”

Israeli foreign ministry spokesman Yigal Palmor denied any Israeli involvement.

“Israel has nothing to do with this incident,” Mr. Palmor said. “These automatic accusations are an innate reflex with Hezbollah. They don’t need evidence, they don’t need facts, they just blame anything on Israel.”

Yuval Steinitz, Israel’s Minister of Strategic Affairs and Intelligence, later told Israel Radio he wouldn’t comment on “rumours.”

“We are used to this habit that with almost everything there is a tendency first to blame Israel,” Steinitz said.

In 1992, Israeli helicopter gunships ambushed the motorcade of Hezbollah leader Sheik Abbas Musawi, killing him, his wife, 5-year-old son and four bodyguards. Eight years earlier, Hezbollah leader Sheik Ragheb Harb was gunned down in south Lebanon.

But one of the biggest blows for the group came in 2008 when Imad Mughniyeh, a top Hezbollah military commander, was killed by a bomb that ripped through his car in Damascus.

Nasrallah, the current Hezbollah leader, has rarely appeared in public since the 2006 war.

Al-Laqis’ killing came a half an hour after Nasrallah ended a three-hour interview with a local television station, in which he accused Saudi Arabia of being behind the Iranian Embassy bombings.
