Is it really government drop the poisonous gas?How do you think?

A BBC correspondent who visited the northern town of Saraqeb was told by eyewitnesses that government helicopters had dropped at least two devices containing poisonous gas.

The government has vehemently denied claims it has used chemical agents.

The US has warned that such a development would be a "red line" for possible intervention.

However, President Barack Obama said the current intelligence on possible chemical weapon usage did not constitute sufficient proof.

Testing samples

In April, Saraqeb, a town south-west of Aleppo, came under artillery bombardment from government positions.

Doctors at the local hospital told the BBC they had admitted eight people suffering from breathing problems. Some were vomiting and others had constricted pupils, they said. One woman later died.

A number of videos passed to the BBC appear to support these claims, but it is impossible to independently verify them.

A doctor who treated the dead woman said her symptoms corresponded to organophosphate poisoning and that samples had been sent for testing.

Both the US and UK have spoken of growing evidence that the Syrian government has used chemical weapons.

Rebel fighters have also been accused of using them. They also have denied this.

The UN says estimates that the two-year-old conflict has left at least 80,000 people dead.

Boston Marathon explode:has lead at least three people death and 130 injured

Police have confirmed two explosions at the Boston Marathon. The Boston Police are reporting at least three people are dead. More than 130 others are injured.

The dead included an 8-year-old boy, according to two law enforcement sources, the Boston Globe is reporting.

Boston police say no suspect has been taken into custody in connection with the explosions near the finish line of the Boston Marathon, despite reports from the New York Post of a 20-year-old suspect under guard at an undisclosed Boston hospital.

Police Commissioner Edward Davis also says the fire at a library a few kilometres away and more than an hour later doesn’t appear to be related to the explosions at the race on Monday. He says the fire may have been caused by an incendiary device.

A searchable list of Canadians in the race is at the bottom of this story.

Police say it’s too early to get into specifics about the nature of devices or whether shrapnel was involved.

Bloody spectators near the finish line of the Boston Marathon were being carried to the medical tent that had been set up to care for fatigued runners. Police wove through competitors as they ran back toward the course. Many of the injured suffered devastating injuries.

“These runners just finished and they don’t have legs now,” Roupen Bastajian, 35, a Rhode Island state trooper and former Marine, told the New York Times. “So many of them. There are so many people without legs. It’s all blood. There’s blood everywhere. You got bones, fragments. It’s disgusting.”

“There are a lot of people down,” said one man, whose bib No. 17528 identified him as Frank Deruyter of North Carolina.

He was not injured, but marathon workers were carrying one woman, who did not appear to be a runner, to the medical area as blood gushed from her leg. A Boston police officer was wheeled from the course with a leg injury that was bleeding.

An image of a fireball and smoke were shared on Twitter as well as what appears to be blood on the ground at the site of the reported explosion.

“There are people who are really, really bloody,” said Laura McLean, a runner from Toronto, who was in the medical tent being treated for dehydration when she was pulled out to make room for victims of the explosions. “They were pulling them into the medical tent.”
