Egypt on Friday welcomed Saudi Arabia's decision to list the Muslim Brotherhood as a terrorist organization and called on other Arab countries to follow suit.

The Saudi move further isolates the Brotherhood of deposed Egyptian president Mohamed Mursi, already designated by Egypt as a terrorist group following a suicide bombing that killed 15 people in a police station in December.

The group condemned the bombing and has denied involvement in any of the violence rocking Egypt since Mursi was ousted by the military in July.

"We welcome the Saudi decision ... which shows the depth of cooperation and solidarity between the two countries," Egypt's foreign ministry spokesman Badr Abdelatty told AFP.

Saudi Arabia hailed Mursi's overthrow and pledged billions of dollars to Egypt's military-installed interim government.

"We look forward to see other countries which signed the 1998 Arab League counter-terrorism treaty follow the Saudi path and respect their commitments under the treaty," Abdelatty added.

The agreement has been ratified by 18 of the Arab League's 22 members, an official of the Cairo-based organization previously told AFP.

The Brotherhood, the largest Islamic movement in the region with a presence in most Arab countries, said it was "surprised" and "pained" by the Saudi decision.

"This new position the kingdom contrasts sharply with the history of its relations with the Brotherhood," the group said.

"History has always shown that the Brotherhood has been a leader in spreading true Islamic thinking ... without extremism, as many of the kingdom's scholars and leaders can testify."

Mursi and dozens of Brotherhood leaders face trial in Egypt on a number of charges, including collusion with militants to carry out attacks.
