New pictures show the moment of impact as an Israeli missile hit a Beirut apartment block and exploded.
The block was one of five buildings destroyed by airstrikes on Friday alone.
Israel launched airstrikes in the southern suburbs of Beirut in a fourth consecutive day of intense attacks.
There were no immediate reports of casualties.
An Associated Press photographer captured a sequence of images showing an Israeli bomb approaching and hitting a multi-storey apartment building in Beirut’s Tayouneh area.
Richard Weir, a senior crisis, conflict and arms researcher at Human Rights Watch, reviewed the close-up photos to determine what type of weapon was used.
“The bomb and components visible in the photographs, including the strake, wire harness cover, and tail fin section, are consistent with a Mk-84 series 2,000-pound class general purpose bomb equipped with Boeing’s joint directed attack munition tail kit,” he told AP.

Deadly strikes as bombardment stepped up
Israel stepped up its bombardment this week – an escalation that has coincided with signs of movement in US-led diplomacy towards a ceasefire.
The Israeli military said its fighter jets attacked munitions warehouses, a headquarters and other Hezbollah infrastructure. It issued a warning on social media identifying buildings ahead of the strikes.
Meanwhile, an Israeli airstrike killed five members of the same family in a home in Ain Qana in the southern province of Nabatiyeh, Lebanon’s state media said.
The report said a mother, father and their three children were killed but didn’t provide their ages.

Three other Israeli strikes killed six people and wounded 32 in different parts of Tyre province on Friday, also in south Lebanon, the report said.
Video footage also showed a building being struck and turning into a cloud of rubble and debris that billowed into Horsh Beirut, the city’s main park.

More than 3,200 people have been killed in Lebanon during 13 months of fighting between Israel and Hezbollah – most of them since mid-September.
About 27% of those killed were women and children, according to Lebanon’s health ministry.
Israel dramatically escalated its bombardment of Lebanon from September, vowing to cripple Hezbollah and end its barrages in Israel.
Friday’s strikes come as Lebanon’s caretaker prime minister has asked Iran to help secure a ceasefire in the war between Israel and Hezbollah.
The prime minister appeared to urge Ali Larijani, a top adviser to Iran’s supreme leader, Ali Khamenei, to convince the militant group to agree to a deal that could require it to pull back from the Israel-Lebanon border.
Iran is a main backer of Hezbollah and for decades has been funding and arming the Lebanese militant group.
On Thursday, Eli Cohen, Israel’s energy minister and a member of its security cabinet, said that prospects for a ceasefire with Lebanon were the most promising since the conflict began.
The Washington Post reported Israel’s Prime Minister Benjamin Netanyahu was rushing to advance a Lebanon ceasefire to deliver an early foreign policy win to his ally, US President-elect Donald Trump.
