A coup was attempted in Turkey Friday with a faction of the military taking over state TV, imposing martial law and a curfew and reportedly attacking the police headquarters in the capital of Ankara, according to American and foreign officials.

“The situation unfolded in Turkey was a coup attempt to overthrow the democratically-elected government,” read a statement released by the Turkish embassy in Washington, D.C., late Friday night. “This attempt was foiled by the Turkish people in unity and solidarity. Our President and Government are in charge. Turkish Armed Forces was not involved in the coup attempt in its entirety. It was conducted by a clique within the Armed Forces and received a well-deserved response from our nation.”The state-run Anadolu news agency said at least 90 people were killed in clashes and more than 1,100 were wounded.

Anadolu Agency also reported Saturday morning that 1,563 members of armed forces have been detained across the country. The number of those detained steadily increased Saturday: two hours before that figure was released, the number of detained was 754.

According to the Ministry of Interior, 29 colonels and 5 generals were relieved of their duties.

About 200 unarmed soldiers left Turkey’s military headquarters and surrendered to police, Anadolu Agency reported.

There were also at least two blasts reported near the entrance to parliament and no immediate word of casualties. The entrance to the building appears damaged.

Late Friday night, the country’s president, Recep Tayyip Erdogan, returned to Istanbul after going to an undisclosed location and vowed that those who carried out the coup will “pay.” Earlier, he urged supporters to take to the streets in defiance.

Upon arrival at Istanbul’s Ataruk Airport, Erdogan addressed thousands of flag-waving supporters, saying the coup won’t succeed. “They have pointed the people’s guns against the people,” he said. “The president, whom 52 percent of the people brought to power, is in charge. This government brought to power by the people, is in charge. They won’t succeed as long as we stand against them by risking everything.”
