Here's an item from our news desk on various commemoration ceremonies that are being held today to honor the victims of the MH17 air disaster:
Memorial services were being held in Ukraine, Australia, and the Netherlands on July 17 to mark the first anniversary of the MH17 airline disaster that killed 298 people.
Malaysia Airlines Flight 17 was carrying 193 Dutch citizens, 43 Malaysians, 38 Australian citizens and residents, 12 Indonesians, and 10 Britons when it was shot down near the village of Hrabove in eastern Ukraine.
Residents of Hrabove marched in a procession to the crash site to mark the anniversary and unveiled a memorial stone ahead of a service there.
In Australia, Prime Minister Tony Abbott unveiled a plaque in the gardens of Parliament House in Canberra with the names of the Australian citizens and residents who were killed.
The plaque, set in soil brought back from the crash site by an Australian police officer, says, "In memory of the lives of those who called Australia home, lost in the downing of Flight MH17 on 17 July 2014."
At a national service held inside the parliament building's Great Hall, Abbott said Australians owed it to the dead to bring the guilty to justice.
Of the victims, Abbott said: "Their passing leaves a void that can never be filled and a pain that still throbs."
In the Dutch city of Nieuwegein, relatives of victims planned on July 17 to read out the names of all the Dutch citizens who were killed.
Malaysia held a memorial service on July 11 because the anniversary comes on a holiday marking the end of Ramadan.
In Britain, the online investigative journalism website Bellingcat created a special page called @mh17live that is reenacting the social-media reaction to the MH17 tragedy.
On the morning of July 17, the website reproduced year-old social-media posts from eastern Ukraine by people who were tracking the movement of a Russian Buk missile launcher hours before the MH17 was shot down and in the hours after the crash.
According to leaks from a draft investigative report, a Dutch-led team of international investigators believe the evidence suggests the plane was brought down by a Russian surface-to-air missile that likely was fired by pro-Russian separatists.
U.S. officials from the Office of the Director of National Intelligence have said there is a "solid case" that the plane was brought down by a Russian SA-11 missile, also known as a Buk missile.
They say the missile was fired from separatist-controlled territory in eastern Ukraine under "conditions the Russians helped create."
But Russia and the separatists deny any responsibility, blaming Ukrainian government forces for the downing of the airliner.
In Kyiv, Ukrainian President Petro Poroshenko said in a July 17 video message posted on his official website that "the high-tech weapons used to down the plane" come only have come from Russia.
Poroshenko said the people of Ukraine took the crash as their own personal tragedy.
He vowed that those responsible for the tragedy would be punished, saying "murderers must know that the punishment can't be avoided."
Poroshenko also said: "This crime poses a threat to the entire international community."
He also noted that Ukraine, Australia, Belgium, Malaysia, and the Netherlands have recently asked the United Nations Security Council to found an international criminal tribunal that would try the chief suspects after the Dutch-led international investigation publishes its definitive final report in October.
Russian President Vladimir Putin, whose country wields veto power on the Security Council, on July 16 told Dutch Prime Minister Mark Rutte in a telephone call that setting up a UN tribunal to prosecute the suspects would be "premature" and "counterproductive."
Rutte has said a UN tribunal would give "the best guarantee of cooperation from all countries" in seeking justice for the families of the victims.
Meanwhile, the European Union's foreign policy chief, Federica Mogherini, said in a statement on July 17 that "Those directly or indirectly responsible for the downing of MH17 must be held accountable and brought to justice in accordance with UN Security resolution 2166."
Mogherini said the EU and its member states fully support "the ongoing efforts to establish a binding and credible prosecution mechanism."
