(QHA) -

As Moscow solidified its hold on Crimea this week, prominent Russian map publishers are rushing to show the Black Sea peninsula as Russian territory, RFE/RL reports.

The daily "Izvestia" quoted the publisher's owner and director, Sergei Melikov, as saying the new maps will be available in retail stores in about two weeks.

Likewise, the Russian Geographic Society says it will include Crimea as part of Russia in its maps, ITAR-TASS reports.

Meanwhile, two of Russia's biggest Internet companies have also started updating their mapping tools to designate Crimea as part of Russia.

Some U.S. media, including "The Washington Post" and "U.S. News and World Report," claimed that the National Geographic Society would show Crimea as part of Russia as soon as the State Duma ratifies the annexation.

Other American mapmakers continue to show Crimea as part of Ukraine. As of March 20, for example, Google maps showed Crimea as part of Ukraine.

Secretary of State John Kerry and President Barack Obama have declared Crimea's referendum on secession – approved by around 97 percent of voters Sunday – as illegal and invalid because it was conducted in violation of Ukraine’s constitution. They also say Russia is violating international law by occupying the region.
