American billionaire Elon Musk announced this Monday evening the purchase of Twitter for an estimated amount of 43 billion US dollars, according to several American and international media outlets.

Elon Musk tweeted on Twitter saying: "Twitter is ours: confirming the end of negotiations between the two sides to officially buy the company, at a time when the CEO of Tesla described his offer as the "best and final" for the social networking company, according to Reuters, citing sources familiar with the matter.

In breaking news, Reuters said Elon Musk will acquire Twitter and shareholders will receive $54.20 per share under the agreement.

Adding that "Twitter" will become a private company once the acquisition deal with Elon Musk is completed.

Explaining that Musk's acquisition deal for Twitter will amount to approximately 44 billion dollars at a rate of $54.20 per share.

Meanwhile, Twitter confirmed that Elon Musk has become fully controlling the company.

According to Al Jazeera website, Twitter's board is negotiating with Musk in the early hours of Monday regarding his unwelcome attempt to buy the company, especially after he began raising $46.5 billion to finance the offer last week, according to sources who spoke on condition of anonymity because they were not authorized to discuss "confidential" information.

These sources said that securing funding commitments was a turning point in how the board viewed Musk's $54.20 per share offer, enabling the company's 11 board members to seriously consider his offer.

Musk, who has more than 83 million followers on Twitter and began accumulating shares in the company earlier this year, announced his intention to buy the company on April 14 and take it private.
