LONDON, June 24 (Xinhua) -- British Prime Minister David Cameron and U.S. President Barack Obama on Tuesday discussed the latest crises in Ukraine and Iraq in a phone call, Downing Street announced Tuesday.
"President Obama called the Prime Minister to discuss the latest developments in Ukraine and Russia's response. Both leaders welcomed the efforts taken by President Poroshenko to establish a ceasefire in Eastern Ukraine," a Downing Street spokesperson said following the phone call.
The two leaders noted that while Russian President Vladimir Putin had called on the militants to accept the ceasefire, they "had yet to see concrete action from Russia to halt the flow of weapons across the Ukrainian border and to stop Russian training of separatist groups," according to the spokesperson.
Cameron noted that he would discuss this issue with other European leaders at the upcoming European Council and would press for "preparatory work" on further sanctions to continue, the spokesperson added.
Russia's upper house of the parliament is to revoke a resolution on military intervention in Ukraine on Wednesday at the request of Putin, the Kremlin announced Tuesday.
Putin asked Speaker Valentina Matviyenko of the upper house to cancel the March 1 resolution to facilitate the normalization of the situation in eastern Ukraine, Kremlin spokesman Dmitry Peskov said.
The parliamentary body is set to approve Putin's request on Wednesday.
Ukrainian President Petro Poroshenko said Putin's request is "the first practical step" after the Russian leader made statements to support Ukraine's proposed peace settlement plan.
In the phone call, Cameron and Obama also discussed the situation in Iraq and the "grave threat posed by ISIL (the Islamic State of Iraq and the Levant) to the national security of both the United Kingdom and the United States."
They agreed that the Iraqi government needs to pursue "a more inclusive approach that engages Sunni, Shi'a and Kurdish communities."
They also agreed on the need for the Iraqi security forces to prevent further ISIL advances, the spokesperson said, adding that Cameron welcomed Obama's decision to send up to an additional 300 U.S. military advisors to "assess how the U.S. can best support the efforts of Iraqi forces."
"In the longer term, they agreed that we would need to work with partners in the region to tackle the threat from ISIL in the region," the spokesperson noted.
Last week, Obama announced that as many as 300 U.S. military advisors would be sent back as part of effort to help Baghdad confront the surprise advances by fighters from the ISIL.
U.S. Secretary of State John Kerry on Tuesday arrived in Iraq's semi-autonomous region of Kurdistan to discuss the Iraqi situation with the Kurdish leaders, official Iraqi television reported.
His visit came amid worsening security scenarios in Iraq that started about two weeks ago when armed Sunni insurgents embarked on surprise offensives resulting in the retreat of Iraqi security forces and the seizure of large swathes of territories in the country.
