President Vladimir Putin had no plan to meet the head of Greenpeace International, whose environmental activists have been detained and charged in Russia, the Kremlin said Thursday.

"There is no such event on (Putin's) schedule," Kremlin spokesman Dmitry Peskov told reporters.

Western media reported last month that Greenpeace executive director Kumi Naidoo had sent a letter to Putin on Oct. 9, asking for a meeting and offering himself "as security" for the activists' release on bail.

Peskov said Putin was informed about the letter but "unfortunately" not all letters had reached the Kremlin administration.

Greenpeace vessel Arctic Sunrise was detained on September 19 after activists aboard attempted to stage a protest against oil drilling at Prirazlomnaya platform in the Pechora Sea. The vessel was brought to Murmansk by Russian coast guards.

In mid-October, a group of 11 Nobel Peace Prize laureates asked Putin to drop charges against the 30 people arrested. The president's administration replied the plea should be directed to the judiciary.

Also on Thursday, Russian Investigative Committee spokesman Vladimir Markin said several Arctic Sunrise crew members would be charged with resisting police in addition to the charges of hooliganism brought earlier.

Markin said the committee had asked a court to arrest all 30 activists because they refused to cooperate with the investigators in the early stages.

"We were not interested in who was a cook and who was a photographer, because none of them spoke to the investigators (about their roles)," Interfax news agency quoted Markin as saying.
