Jerusalem: Israel has "no doubt" the fatal shooting attack at the ticket counter of its national airline El Al at the Los Angeles airport was a "terrorist" act, a senior Israeli official said on July 5.

"There's no doubt (for Israel) that the shooting at El Al counter at Los Angeles airport was a terrorist attack," the senior official said on condition he not be named. "We're now waiting for the official results of the investigation."

The man who killed two people on July 4 at Los Angeles international airport before he was killed by airline security guards was of Egyptian origin, according to the US television network CNN, quoting Federal Bureau of Investigation (FBI) sources.

US officials said the shooting appeared to be an isolated incident but did not rule out terrorism, as the country remained blanketed under an "elevated" level of alert for the July 4 Independence Day holiday, the first since the September 11 attacks.

In its Friday English-language edition, the Israeli newspaper 'Haaretz’ reported that the internal Shin Beit security service "decided to be circumspect and label it a hostile terrorist act" while awaiting a final verdict.

"The way in which the attack took place, its location and timing, seemed to point to terrorism. Unless proved otherwise, that is how the Shin Beit decided to regard it," said 'Haaretz'.

'Haaretz' military correspondent Amos Harel also raised the spectre that Arabs might resume "terrorism" against Israel on an international scale.
