LOS ANGELES - Hundreds of students in several US states, including California and Maryland, walked out of classrooms on Monday to protest Donald Trump's election as president.

Students in east Los Angeles, some of them carrying signs that read "Rise Up" and "Together We Stand" as well as American and Mexican flags, marched peacefully to a plaza in Boyle Heights, a predominantly Hispanic neighborhood.

Similar marches were organized in Portland, Oregon as well as in Silver Spring, Maryland, reflecting the emotions that are still running high one week after Trump's presidential win.

The protest in Los Angeles took place despite calls by school officials for students not to walk out of classes and to find other ways to express their anger at the election result.

In Maryland, local media showed hundreds of students from five high schools marching through the city of Silver Spring, some carrying signs that read "Not My President" and at times blocking traffic. Bystanders shouted words of encouragement while some motorists honked their horn in approval.

The students could be heard chanting "we reject the president-elect."

Meanwhile, US President-elect Donald Trump and Russian President Vladimir Putin spent some time on the telephone Monday, as the two leaders discussed hopes that they can thaw icy relations that have endured for years.

The Kremlin confirmed that the two leaders spoke by phone Monday and that both Trump and Putin agreed that US-Russian relations are presently at an "unsatisfactory" level.

Trump's campaign said Putin had called to offer his congratulations on winning the election and the two began discussing a range of issues. The Russian leader had sent Trump a telegram immediately after the victory.

It remains to be seen exactly how relations might improve under Trump's administration.

For years, Washington has feuded with Moscow over a spate of issues, including human rights and corruption, as Russia continues to deal with economic sanctions imposed by Obama's administration.

Russian officials and citizens have expressed happiness with Trump's victory, as they feared Hillary Clinton might continue the status quo on foreign policies.

Syria was another topic the two leaders talked about Monday. For many months, Russia and Syrian President Bashar Assad have been allied in their fight against opposition rebels and militants. Washington, though, has supported the rebels in the country's five-year civil war.

In its statement, the Kremlin said the two leaders share a common goal of "uniting efforts in the fight with the common enemy number one -- international terrorism and extremism."

Clinton criticized Trump over his praise of Putin during the campaign. She and other Trump critics pointed to a US intelligence assessment that Russian interests were behind the hackings of US Democrat Party members and may have tried to influence the elections.

Putin denied the allegations. Trump also expressed skepticism, and said the United States should seek better relations with Putin and Russia.

The Russians said that Putin and Trump "agreed to continue contacts on the phone and in the future to provide for a personal meeting."

The Trump team said that he "noted to President Putin that he is very much looking forward to having a strong and enduring relationship with Russia and the people of Russia."
