A child was among at least nine killed in the blasts, which injured around 2,800 people, Lebanese Health Minister Firass Abiad said. At least 170 people are in a critical condition, he said, though the nature of the other injuries is unclear.

Videos circulating on social media and news agencies appear to show powerful explosions in various locations. In one CCTV video, a man can be seen picking out fruit in a supermarket when an explosion tears his bag to shreds. Bystanders can be seen running away as they hear the explosion, while the man drops to the ground clutching his lower abdomen. After several seconds, he can be heard groaning in pain.

Other social media videos showed large numbers of injured people, including at least one child. Those wounded were covered in blood, some with facial and hand injuries as well as flesh wounds.

The incident comes amid increased hostility between Hezbollah and Israel, and raises tensions in the region further. Both Lebanon and Hezbollah have blamed Israel for the explosions.

“This criminal and treacherous enemy will definitely receive a fair punishment for this sinful assault, both in ways that are expected and unexpected,” Hezbollah said Tuesday evening, vowing retribution.

The militant group had earlier confirmed on its Telegram channel that “workers” in various Hezbollah institutions were affected by the explosions, with a “large number” of people injured.

Iran’s Ambassador to Lebanon, Mojtaba Amani, was among those wounded in Beirut, along with two embassy employees, according to Iranian state media. Amani has a superficial injury and is currently under observation in the hospital, state media IRNA reported, citing his wife.

Lebanon’s Prime Minister Najib Mikati slammed the attack as “a serious violation of Lebanese sovereignty and a crime by all standards” in a cabinet meeting on Tuesday, according to the state-run NNA news outlet.

The Israeli military, which has engaged in tit-for-tat strikes with Hezbollah since the start of the war in Gaza last October, said it would not be commenting on the incident.

In a statement following the pager explosions, the Israel Defense Forces also said it had no changes in its advice to Israeli civilians. “The public are asked to remain alert and vigilant, and any change in policy will be updated immediately,” it said in a statement.
