US has welcomed the release of two Americans who had been held hostage by Houthi rebels from the beginning of this year.

The hostages are now free and in neighboring Oman, according to the White House. They were flown to Muscat with an Omani government plane and were met by U.S. consular staff, officials said.

A third American who was believed held by the Houthis was not released, and it's unclear exactly who has him, a senior administration official told CNN on Sunday.

"We will continue to work tirelessly to pursue the release of all Americans detained abroad unjustly, including those who remain in the region," US Secretary of Kerry said in a statement.

He thanked the Omani government Sunday, adding that the US government welcomed the hostages' release and would keep pushing for the release of other detained Americans.

Two Americans, a British and three Saudis, who were detained by houthis for several months, were released earlier and arrived in Oman.
