Countries from across the globe, including the US, Russia, Australia, France, Saudi Arabia, Sri Lanka and Bangladesh, have condemned the brutal Pulwama terror attack carried out by Pakistan-based terror group Jaish-e-Mohammad (JeM) and extended support to India in the fight against terrorism.

At least 40 CRPF personnel were killed and many injured on Thursday in one of the deadliest terror attacks in Jammu & Kashmir when a Jaish-e-Mohammad (JeM) suicide bomber rammed a vehicle carrying over 100 kg of explosives into their bus in Pulwama district.

Condemning the attack, Russian President Vladimir Putin on Friday said perpetrators and sponsors of the attack should be brought to book and reiterated his country's support for further strengthening counterterrorist cooperation with India.

In a message to President Ram Nath Kovind and Prime Minister Narendra Modi, Putin said, "Please accept the most sincere condolences in connection with the loss of Indian law enforcement officers in the terrorist act in the state of Jammu & Kashmir. We strongly condemn this brutal crime. The perpetrators and sponsors of this attack, undoubtedly, should be duly punished.

"I would like to reiterate the readiness for further strengthening counterterrorist cooperation with Indian partners. In Russia, we share the grief of friendly people of India and hope for speedy recovery of the injured," he said.

The US specifically singled out Pakistan in its statement condemning the attack.

In a stern message to Pakistan, the White House has asked Islamabad to "immediately end" its "support" to all terror groups and not to provide "safe haven" to them.

"The US calls on Pakistan to end immediately the support and safe haven provided to all terrorist groups operating on its soil, whose only goal is to sow chaos, violence, and terror in the region," White House Press Secretary Sarah Sanders said in a statement. "This attack only strengthens our resolve to bolster counterterrorism cooperation and coordination between the US and India," she said in the statement issued by the White House.

Oz political leaders also condemned the "heinous" terror attack. "We convey our deepest condolences to the families of the victims, and all those injured. Our thoughts are with my friend Prime Minister @narendramodi and the Indian people," Prime Minister Scott Morrison tweeted on Friday.

Opposition leader Bill Shorten said it was an atrocious attack. "To the family and friends of the soldiers killed and injured — we send our deepest condolences, support, and hope for a timely recovery for the injured," he said in a statement.

Saudi Arabia said it stood with India's fight against terrorism and extremism and denounced as "cowardly" the suicide attack. The strong condemnation came days ahead of Saudi Crown Prince Mohammed bin Salman bin Abdulaziz Al Saud's state visit to India next week for talks with the top Indian leadership.
