Egypt's National Security Service has foiled a planned attack against a foreign vessel in the Suez Canal, the MENA news agency reported.
Officers detained two suspects -- residents of the Ismailia region. One of them planned an attack on a vessel passing through the canal from a land plot he owned on the coast.
The agency said the suspects intended to 'inflict damage upon the state's economy'.
The Suez Canal linking the Mediterranean Sea and the Red Sea is a key source of funding for Egypt's budget. The country receives around $5 billion annually in levies for the passage of vessels.
Despite political instability in Egypt since the Hosni Mubarak regime was deposed in February 2011, the canal has operated normally. Around 50 ships pass through the canal daily.
