Washington: US President Barack Obama on Tuesday called for a G7 summit next week to discuss the escalating showdown with Russia over Crimea.
The White House said Obama asked fellow leaders of the grouping -- minus G8 member Russia -- to join him in the Hague, where he will be attending a nuclear security summit, to discuss the crisis and how to support Ukraine.
"The United States and the other members of the G7 have already suspended our preparations for the G8 Summit in Sochi," said National Security Council spokeswoman Caitlin Hayden.
"Today President Obama invited his counterparts from Canada, France, Germany, Italy, Japan, the United Kingdom, and the EU to a meeting of G7 leaders next week on the margins of the Nuclear Security Summit in The Hague.
"The meeting will focus on the situation in Ukraine and further steps that the G7 may take to respond to developments and to support Ukraine."
