The number of officers jailed now stands at 20 - including five admirals and three generals.

The court ordered the jailing of eight more officers, including five active duty officers and two generals, pending trial Thursday.

The arrests came ahead of a critical meeting of  Turkey´s president, the military chief and the prime minister.

They were expected to discuss tensions over the largest-ever crackdown on the military in Turkey.

In total, eight out of 20 officers arrested were on active duty.

Prosecutors say the military drafted plans in 2003 to topple the AK Party government.

The investigation into the alleged plot led to the detention of about 50 commanders Monday.

Among them are former chiefs of the Navy, Air Force and Special Forces.
