President Corazon Aquino ordered the court martial Saturday of the leader of the seventh uprising against her and urged the Philippine Congress to swiftly pass a law increasing penalties for rebellion.

In a nationally televised address, Aquino announced the unconditional surrender of Army Col. Alexander Noble after his 48-hour takeover of two cities in Mindanao and his proclamation of the country's second largest island as an independent federal republic."There was no way out unless he was willing to die. Obviously he was not willing to die," said Aquino, who has crushed six other coup attempts since she took power in a civilian-backed military revolt in 1986.

"He miscalculated, mistaking the sound from his own band of civilian cheerleaders as people's acceptance. He miscalculated in expecting that corollary supportive action from fellow renegades and mercenaries would follow," Aquino said.

Hours after Noble's surrender, one person was wounded in an explosion that ripped through a jeep parked inside suburban Camp Aguinaldo, the Philippine Armed Forces headquarters.

Armed Forces chief Gen. Renato de Villa said troops remain on the maximum state of readiness clamped on military camps across the nation following the rebellion in Mindanao.

Noble, 42, Aquino's former deputy security chief, walked out at 3 a.m. at the garrison in Cagayan de Oro in Mindanao, 500 miles south of Manila, he had occupied since Thursday after taking Butuan east of the city.

Accompanied by priests and local officials who negotiated his surrender, Noble gave up to Sen. Aquilino Pimentel, a former mayor of the city.
