He said unlike other countries which had taken drastic action to protest against the alleged spying, Malaysia has been slow to react, sending only a protest note from the Foreign Ministry.
"To date, there is no statement from the prime minister. He is not brave to reprimand the rudeness and unacceptable conduct of the United States," he said when debating the Budget 2014 which is currently at the committee stage.
Snowden had alleged that the US was running a monitoring station in its Kuala Lumpur embassy to tap telephones and monitor communication networks.
Last month, Australian intelligence sources confirmed that XKeyscore, a top secret intelligence tool revealed by Snowden, had been used to spy on Malaysia and other Asia-Pacific countries.
The latest report on top secret documents leaked by Snowden, who currently has been granted by Russia, revealed that there are 90 electronic surveillance facilities worldwide, including in the US embassies in Jakarta, Bangkok, Phnom Penh and Yangon.
Following the revelations, Foreign Affairs Minister Datuk Seri Anifah Aman told Australian counterpart Julie Bishop that spying should not take place among "close friends as it could severely damage existing relations".
Anwar also raised his concerns over the recent revelation by former prime minister Tun Dr Mahathir Mohamad over the presence of CIA agents in the Attorney General’s Chambers.
"I don't understand why no one, especially Umno MPs, raised this matter. Since Dr Mahathir had spoken about this, there should be a clear explanation, if they are not CIA agents, then what are they doing in the AG’s Chambers," he said.
He then trained his guns on the Attorney General Tan Sri Abdul Gani Patail, saying that the country lost its case on Pulau Batu Puteh in the International Court of Justice because Gani prepared a photo which showed a wrong location of the island.
The International Court of Justice awarded the island off Johor to Singapore after a legal dispute in 2008.
"He was never questioned about this. I don't understand, either there seemed to be an understanding or they are afraid to ask him to explain," Anwar said, adding that the public was entitled to an explanation from Gani on the allegations surrounding him and his office.
Earlier this month, Anwar had said Gani should be suspended immediately in the wake of the allegations which were contained in a statutory declaration by former Kuala Lumpur CID chief Datuk Mat Zain Ibrahim.
It was reported that three months ago, Dr Mahathir, Mat Zain, prominent lawyer Tan Sri Muhammad Shafee Abdullah and Federal Commercial Crimes Investigation Department director Datuk Ramli Yusoff held a meeting at the former prime minister's residence to discuss Gani's alleged misdeeds.
The meeting was held on August 10, three days after Hari Raya Aidilfitri, and among the topics discussed was the highly publicised case of Pulau Batu Puteh. – November 18, 2013.
