The official death toll from Russian authorities in the wake of Friday's terror attack on a Moscow concert hall has reached 133 killed, with some unofficial reports saying there could be as many as 140 or more. As the scene continues to be processed and investigated, and given some of the hospitalized are in critical condition, the death toll is likely to rise. Over 150 were wounded in the attack, which involved a group of well-equipped attackers sporadically shooting into crowds as they walked through the mall and into the concert hall.

Russian president Vladimir Putin, who was reelected last weekend, accused Ukraine of being tied to the Moscow terror attack on Friday that killed at least 133 people and injured more than 100 others.

In a five-minute televised address released Saturday, Putin told Russian citizens that four suspects who directly participated in the shooting on Moscow’s Crocus City Hall were detained near the country’s border with Ukraine. The Russian leader asserted they tried escaping to Ukraine, which was allegedly preparing to receive them after the attack.

Russia’s security services say they have arrested four gunmen responsible for the shooting that killed at least 115 people at a concert hall on the outskirts of Moscow, in one of the worst terror attacks in the country’s history.

The director of Russia’s federal security service (FSB) informed Vladimir Putin that 11 individuals had been arrested in connection with Friday’s terrorist attack at the Crocus City Hall outside Moscow, including four suspects involved in the shooting.

Russian authorities said they had detained 11 people in connection with a terrorist attack on a concert hall in a Moscow suburb, as the death toll from the Friday night assault rose to 115, investigators said.

Among those taken into custody were four people who prosecutors said played a direct role in the violence, in which gunmen shot audience members at close range and set off smoke bombs.

Russia’s Investigative Committee has claimed that the number of deaths following Friday evening’s massacre at the Crocus City concert hall near Moscow has been confirmed at 115 people and warned that this figure is likely to rise.

The service had previously stated that the death toll was 93, but later issued an update announcing that additional bodies were found after emergency services started clearing the rubble.

At least 28 people were killed on Wednesday by two separate bomb blasts outside the offices of election candidates in southwestern Pakistan, on the eve of a national vote marred by violence and allegations of poll rigging.

More than half a million security officers were deploying ahead of Thursday’s election, with authorities distributing ballot papers to more than 90,000 polling stations.

There have been multiple security incidents in the run-up to the vote, with at least two candidates shot dead and dozens more targeted in attacks across the country.

Two bombs in Pakistan’s southwestern province of Balochistan have killed at least 28 people, officials said, with dozens more injured.

The twin blasts on Wednesday came a day before elections. The attacks targeted the election offices of political parties in the restive region.

The first blast, which killed 16 people, took place at the office of independent election candidate Asfandyar Khan Kakar in Pishin district near the border with Afghanistan, said Jan Achakzai, Balochistan’s caretaker information minister. More than 20 people were reported wounded.

Terrorists attacked two campaign offices in Pakistan’s restive western Balochistan province on Wednesday, a day before the country’s general election, killing 29 people and wounding 40 others.

Seventeen people died and 30 were wounded in the first attack, which took place shortly after noon local time when a suicide bomber struck the campaign office of Asfandyar Khan Kakar, a former minister and independent candidate for the provincial assembly constituency of Pishin, a district close to Pakistan’s border with Afghanistan.

The U.S. secretly warned Iran that Islamic State was preparing to carry out the terrorist attack early this month that killed more than 80 Iranians in a pair of coordinated suicide bombings, U.S. officials said.

The confidential alert came after the U.S. acquired intelligence that Islamic State’s affiliate in Afghanistan, ISIS-Khorasan, known as ISIS-K, was plotting to attack Iran, they said.

German police officers decked out in heavy tactical gear executed a raid on an apartment building in Duisburg to arrest a man they allege was planning an Islamic terrorist attack on a Jewish event, according to multiple German publications and local police.
