American marines opened fire on protesters who stormed the consulate in Karachi (Reuters)

American Marines opened fire over the weekend against demonstrators during the assault on the U.S. consulate in Karachi, Pakistan, in the context of massive protests triggered by the killing of Iranian Supreme Leader Ali Khamenei, Reuters reports. This is a rare use of force at a diplomatic post, which could suddenly escalate tensions in the country amid widespread protests over the killing of Iran's leader.

Ten people were killed during the assault on the outer wall of the consulate.

U.S. officials confirmed the involvement of the Marines, but it is unclear whether the gunfire caused any casualties.

The provincial government stated that security personnel opened fire, without specifying their affiliation. The protests, which led to a ban on public gatherings in Pakistan, were marked by anti-American and anti-Israeli chants.

Video footage showed violence and gunfire, and community leaders called for the continuation of protests, despite the imposed restrictions.
