Obama: All parties in Turkey should support Erdogan gov't

In a statement issued after a meeting with his national security advisers Friday, Obama also urged everyone in Turkey to show restraint and avoid violence or bloodshed.

Obama discussed the developments by telephone with Secretary of State John Kerry, who was traveling in Moscow for separate meetings with senior Russian officials on Syria.

The Defense Department also released a statement saying it is "taking appropriate steps to ensure the safety and security of our service members, civilians, their families and our facilities."

The former secretary of state echoed Kerry's remarks, saying, "We should all urge calm and respect for laws, institutions, and basic human rights and freedoms — and support for the democratically elected civilian government."
