Security sources told Al-Manar that Shanti was among Al-Qaeda’s group of 13 people who had claimed the responsibility behind Rafik Hariri’s assassination

Lebanese security forces stormed a building in Beirut early Thursday after a nighttime shootout with gunmen holed up inside a flat, in an incident which left two dead and seven wounded.
  
One gunman was killed in the shootout and the body of another man was found inside the flat in west Beirut's Karakass district.
  
Another gunman was wounded, the Lebanese army said in a statement, adding that the man had previously been "detained for several years in Lebanon for security reasons," without elaborating.

Security sources told Al-Manar TV that the name of killed man in incident was Samer Abu Akl, the woman’s name was Gharam Nawrass Al-Hussein. However, the arrested man’s name was Hani Al-Shanti. The sources said Shanti was among Al-Qaeda’s group of 13 people who had claimed the responsibility behind Rafik Hariri’s assassination.

Well-informed sources told Al-Manar that the investigations would focus on the reason why Al-Qaeda group was found in the heart of Beirut.
  
A security official said the spark for the shootout was a personal dispute between at least one of the men and a woman in her early 20s. The dead man and the woman, detained in the incident, were Syrian nationals, he said according to AFP.
  
The army said it also arrested a guard described as "suspicious" and the wounded gunman, having rushed to the site late Wednesday after reports of gunfire.
  
According to the army, the man who was found dead in the flat had been killed during a clash between gunmen that took place prior to the arrival of security forces.
  
Gunmen subsequently lobbed grenades and began shooting at the security forces from the flat, wounding at least six policemen and soldiers. The military said it found a large amount of weapons in the flat.
