A group of Syrian activists hurled eggs and flour at the Syrian embassy in Paris in response to the chemical attack in Khan Sheikhoun, Syria, that killed 73 people and wounded more than 350 on 4 April.

The activists were exiled from Syria for opposing the use of chemical weapons by President Bashar al-Assad's regime. They gathered outside the Syrian Cultural Centre and the Syrian embassy in Paris on 5 April, protesting the strike on rebel-held Khan Sheikhoun in the Idlib province, one of the deadliest of its kind since the Syrian conflict began six years ago.

The victims included 16 women and 27 children, according to Unicef.

Eye-witness Nawras Yagan said the protest was "symbolic" and did not last long as the activists had not obtained a licence from French authorities.

The White House and the UK have blamed Assad's regime for the chemical attack. President Donald Trump described it as an "affront to humanity".

Prime Minister Theresa May called on all third parties involved to "transition away from Assad. We cannot allow this suffering to continue."

Doctors without Borders said there were strong indications that victims of the attack were exposed to two different chemical agents: sarin and chlorine gas.

The World Health Organisation said the strike was "the most horrific since Ghouta in August 2013", when hundreds of people lost their lives.
