Turkey's former army chief will be tried for an alleged plot to topple the government of Prime Minister Recep Tayyip Erdogan.

A Turkish court determined Wednesday that there is sufficient evidence to prosecute former general Ilker Basbug in an alleged Internet campaign aimed at destabilizing Mr. Erdogan's Islamic-based government.

The former general will be tried on the charges of attempting to overthrow the government and forming and directing a terrorist organization.

Basbug is the most senior official arrested in connection with an alleged plot known as Ergenekon. The government alleges the secularist network was planning bombings and other attacks to discredit the Islamic-based government and trigger a military coup.

Turkish authorities have detained more than 300 people including journalists, academics and politicians as part of a wide-reaching investigation into Ergenekon.

The case has highlighted international concerns about press freedom in Turkey.
