Chicago-based Hyatt and its subsidiary Hyatt International Corp. failed to provide adequate security or metal detectors and allowed unauthorized people with explosives easy access to the inside of the hotel, according to the lawsuit filed Monday in Cook County Circuit Court.

"A hotel has a high legal duty to its registered guests to protect them from the foreseeable criminal acts of terrorists," attorney Browne Greene said in a statement. "On Nov. 9, 2005, Hyatt should clearly have had heightened security, rather than the loose security that was in place."

The lawsuit seeks unspecified damages and court costs.

A Hyatt spokeswoman did not return telephone messages left after business hours Monday night.

Suicide bombers detonated bombs almost simultaneously at three Amman hotels, including the Grand Hyatt Amman, where Akkad had been staying, the lawsuit said.

The attacks, which were labeled as "Jordan's 9/11," killed at least 60 people, including Syrian-born Akkad, 75, his 34-year-old daughter and the three suicide bombers. Al-Qaida in Iraq claimed responsibility.

Akkad's three decades of work in Hollywood ranged from the "Halloween" slasher films to more serious movies with Muslim themes.
