Saudi authorities have foiled plans by suspected terrorists to carry out attacks in the kingdom and seized a large cache of weapons and explosives, the Interior Ministry said yesterday.

　　Security forces seized the weapons on Tuesday in the capital, Riyadh, as they were searching for a number of suspects, an unidentified ministry official said. The official, quoted by the state-run Saudi Press Agency, said at least 19 men - including 17 Saudis, an Iraqi holding both Kuwaiti and Canadian citizenships, and a Yemeni - were being sought in connection with the terror plots. He said others were also being sought and their identities would be announced at the appropriate time.
