Thai soldiers detain a pro-government protester while staging a protest against the coup in downtown Bangkok, Thailand, Friday, May 23, 2014. The U.S. is suspending $3.5 million in military aid to Thailand, its first punitive step against the Asian country following a military coup, the State Department announced Friday.

WASHINGTON — The U.S. is suspending $3.5 million in military aid to Thailand, its first punitive step against the Asian country following a military coup, the State Department announced Friday.

Spokeswoman Marie Harf said the department is still reviewing a further $7 million in direct U.S. assistance to Thailand, and an undetermined amount of aid from other global and regional programs.

Secretary of State John Kerry announced the review hours after Thursday's military takeover in Thailand, a U.S. treaty ally and close military partner. Kerry said Thursday there was no justification for the coup and urged the immediate restoration of civilian government and a return to democracy.

Harf said the suspended programs pay for weapons sales and training for military officers.

She said the U.S. has been in contact with Thai military leaders but gave no details.

The declaration of the coup has underscored the limited leverage the U.S. has with Thailand, despite their longstanding ties.

After the military declared martial law on Tuesday, Washington had urged an early return to democracy and free and fair elections, only for Gen. Prayuth Chan-ocha to abruptly seize power.

The new junta consolidated its control Friday.

Ousted members of the former government surrendered and soldiers forcefully dispersed hundreds of anti-coup activists who defied a ban on large-scale gatherings to protest the army's action.

After Thailand's last military coup in 2006, the U.S. suspended programs for a year-and-a-half, totaling more than $29 million, according to the Congressional Research Service. Some programs deemed to be in the U.S. interest continued.
