Jordanian authorities nabbed several suspected terrorists and seized two cars filled with explosives, the state television reported Saturday — the latest arrests involving an Al-Qaeda-linked cell that targeted public institutions and the U.S. Embassy.

Jordan Television (search), quoting an unidentified security source, carried a vaguely worded statement that said authorities were able to "foil the subversive and terrorist attempts which targeted the security and safety of the country."

It said the two cars, which authorities had previously announced were at large, were seized with the explosives and weapons inside them. "Several suspects have been arrested," the statement said.

Government officials were not immediately available for comment.

The government said 10 days ago that several terror suspects were detained when their vehicle, filled with explosives and detonators, was nabbed in a Jordanian town near the Syrian border. It said three additional suspects in two other cars remained at large and that a search was under way to apprehend them.

The officials said the three vehicles entered Jordan from neighboring Syria, claims that Damascus (search) denies.

The suspects rounded up March 31 are believed to be affiliated with al-Qaida, and interrogators were examining if they were specifically linked to Jordanian militant Abu-Musab al-Zarqawi, government officials have said.

The United States has offered a $10 million reward for the capture of al-Zarqawi, who was sentenced to death in absentia Tuesday by a Jordanian military court for leading a conspiracy to kill U.S. aid worker Laurence Foley (search), 60, who was gunned down outside his Amman home in 2002.

Last week's detained suspects have confessed to plotting a series of attacks in the moderate kingdom, a close ally of the United States, the Jordanian officials have said. They said the targets included sensitive public offices, but did not elaborate. However, security has visibly been tightened around government offices, especially the prime and interior ministries.

The U.S. Embassy, where security also has been significantly beefed up, announced this past week that it was another target of the terror plot. The embassy issued a warden message warning citizens to remain vigilant.
