An explosion has hit Sana'a, the capital of Yemen, reportedly resulting in dozens of deaths - with some reports laying the blame on Saudi Arabia.

Footage of smoke and images of destroyed buildings have appeared on social media, with some alleging they are the result of Saudi-led airstrikes.

The explosion occurred at a funeral service being held at a community hall in Sana'a, with the Yemen rebel news agency,, claiming that dozens of civilians had been killed and scores more injured. The funeral was being held for the father of the Minister of the Interior, Major Jalal al-Rowaishan, an ally of the Houthis and former president Ali Abdullah Saleh.

According to Associated Press, the casualties include military and security officials from the ranks of the Shiite Houthi rebels fighting the internationally-recognised government of President Abed Rabbo Mansour Hadi.

Sputnik news agency was also told by a source at the scene that the incident was caused by a Saudi-led bombardment that left dozens of people dead or injured, adding that the alleged airstrike had targeted a funeral hall where Houthi rebels had been paying their last respects to the father of the interior minister.

The total count of those injured and dead may reach the hundreds, the source told Sputnik, according to Russia Today.

The English-language Yemen Post placed the combined death and injury toll at "300+" and posted a series of pictures of a burning building and panicked crowds.

Mhamad Kleit, a reporter for UUnionNews, posted video of a cloud of smoke, along with a tweet identifiying it as the result of Saudi airstrikes as well as footage showing the remains of a building, burning cars and bodies being pulled from rubble.
