Russia has strongly condemned the latest wave of Israel's aerial attacks on Gaza Strip, which has killed over a dozen Palestinians in the besieged territory.
"Further escalation of violence would be impermissible," Russian Foreign Ministry Spokesman Alexander Lukashevich told reporters in Moscow on Thursday.
“The disproportionate strikes in Gaza Strip are totally unacceptable, especially when there are civilian casualties," he added.
"Moscow is deeply concerned with what is going on in Gaza Strip and calls for the bloodshed to end," Lukashevich noted.
The Kremlin also said on Thursday that President Vladimir Putin was following the Gaza situation, and was worried about the violence there.
"President Putin receives online information from all our relevant services in charge of these and, of course, he is concerned with it," Kremlin spokesman Dmitry Peskov said.
The new wave of Israeli aggression on the Gaza Strip has claimed at least 17 lives since Wednesday. Ahmed al-Ja'abari, the popular and influential head of the Hamas military wing, the Ezzedeen al-Qassam Brigades, was assassinated in an Israeli attack on his car on Wednesday.
The Israeli military frequently carries out airstrikes and other attacks on Gaza Strip, saying the actions are being conducted for defensive purposes. However, in violation of international law disproportionate force is always used and civilians are often killed or injured.
Gaza has been blockaded since 2007, a situation that has caused a decline in the standard of living, unprecedented levels of unemployment, and unrelenting poverty.
The apartheid regime of Israel denies about 1.7 million people in Gaza their basic rights, such as freedom of movement, jobs that pay proper wages, and adequate healthcare and education.
