The 29th marks one week since the terrorist attack occurred on the outskirts of Russia's capital, Moscow.
While media outlets connected to the extremist group Islamic State have reported that the attack was carried out by IS, and the US government and others have expressed the view that IS was involved, Russia has further strengthened its claim that Ukraine was involved.
The terrorist attack that occurred on the 22nd at a concert hall on the outskirts of Russia's capital, Moscow, left 143 people dead, making it the deadliest terrorist attack in Russia in the past 20 years.
Four people have been charged so far as the perpetrators, and the Amaq News Agency, which has ties to the extremist group IS (Islamic State), reports that the attack was carried out by IS fighters.
On the 28th, one week after the attack, IS posted on social media praising the crime.
In response, President Putin continues to claim that Ukraine is suspected of being behind the incident, and the Federal Investigative Committee has announced that confiscated items suggest ties to Ukraine.
President Putin has said that ``Ukraine had a 'window' prepared for them to cross the border,'' but according to the state news agency of neighboring Belarus, President Lukashenko said that the perpetrators initially tried to flee to Belarus. He has said that he was.
Moreover, President Lukashenko has said that in a telephone conversation with President Putin, he was asked to close the border on the Belarusian side, and there are discrepancies in his claims.
Ukraine completely denies any involvement, and White House aide Kirby emphasized on the 28th that Russia's claims are "bullshit and propaganda."
Putin's administration has taken various actions, such as further strengthening its claims that Ukraine was involved, to fend off public criticism that the authorities failed to prevent terrorism, and to use this as a pretext for intensifying attacks on Ukraine. It seems that there is a plan.
