Cairo: Egypt's attorney general has added espionage to the charges against 49 alleged Hezbollah agents, in addition plotting to destabilise the country.

Abdel-Meguid Mahmoud told Egypt's state run news agency MENA late Sunday that the alleged agents, including Lebanese, Palestinian, Egyptian and Sudanese nationals, have been spying for a foreign group intending to carry out terrorist attacks in Egypt.

Hezbollah's leader, Hassan Nasrallah, has rejected the accusations but confirmed over the weekend that it had sent a member to Egypt a rare acknowledgment that the Lebanese militant group was operating in another Arab country.
