BEIRUT - Lebanese security forces stormed a building in the capital Beirut early Thursday following a shootout during the night with a man holed up inside a flat, an AFP correspondent at the site said.
The gunman was killed and the body of another man was found inside the flat located on the sixth floor of a building in west Beirut's Karakass district, a security official said on condition of anonymity.
The spark for the incident appears to have been a personal dispute between at least one of the men and a woman in her early twenties.
Both the gunman and the woman, who was detained in the incident, are Syrian nationals, the official said.
The army and police rushed to the site late Wednesday after reports of gunfire.
The man subsequently lobbed grenades and began shooting at the security forces from his flat. At least six police and army troops were wounded.
The shootout came amid heightened tension in Lebanon, where deadly sectarian violence has taken place in the last two weeks linked to the unrest sweeping neighbouring Syria.
The US embassy in Beirut warned American citizens on Thursday to be aware of prevailing "tensions" and "violent incidents" in Lebanon.
In an email to US citizens in Lebanon, the embassy urged them to "continue to monitor news reports, avoid areas where disturbances are reported, and be vigilant about personal security."
Tensions are "high" in Lebanon, the email said, adding that "the potential for protests, road closures, and other violent incidents remains."
Late last week, the Qatari, Emirati, Bahraini and Kuwaiti authorities issued warnings against travel to Lebanon.
