"Americans who celebrate all Armenians were killed in the genocide started 106 years ago," said US President Joe Biden at the White House on April 24.

With this statement, Biden became the first US president to use word genocide in an official statement on the anniversary of the Armenian County Supervisor, a day after informing the Turkish President Recep Tayyip Erdogan

"We do this not to blame that to make sure this will never repeat," he said.

President Joe Biden spoke at the White House on April 20.

The White House boss's statement is considered a big victory for Armenians.

Biden's decision may cause US and Turkish relationships to escalate stress.

The Turkish Foreign Ministry was later million US Ambassador David Satterfield to express dissatisfaction, noted that Biden's decision has hurt the capital relationship that has difficulty healing between the two countries.
