U.S. President Barack Obama has spoken with foreign leaders from Turkey, Israel, Saudi Arabia and the UK on the ongoing situation in Egypt, the White House said on Sunday.

Obama spoke to Turkish Prime Minister Recep Tayyip Erdogan, Israeli Prime Minister Benjamin Netanyahu and Saudi King Abdullah on Saturday, and to UK Prime Minister David Cameron on Sunday, said the White House in a statement.

In his calls, Obama reiterated his opposition against violence and call for restraint, said the White House.

Obama said he supported an "orderly transition" to a government that is responsive to "the aspirations of the Egyptian people," according to the statement.

Anti-government protests persisted for the sixth day across Egypt on Sunday as demonstrators demanded the ouster of President Hosni Mubarak.
