Chemical watchdog 'barred from Syria site'

Macron clarifies 'US to stay in Syria' comments
French President Emmanuel Macron has clarified comments he made in which he claimed to have convinced his US counterpart Donald Trump to keep a military presence in Syria "for the long term".
The White House later said Mr Trump still wanted US troops to leave "as soon as possible".
Mr Macron has now claimed to have "never said" whether the US or France would stay engaged long term in Syria in a military capacity.
But the main aim of both nations remains the "war against ISIS", he added.
Strikes on Syria 'were in national interest'
The Prime Minister will tell MPs this afternoon that the UK acted "because it is in our national interest to do so".
"It is in our national interest to prevent the further use of chemical weapons in Syria - and to uphold and defend the global consensus that these weapons should not be used," she will say.
"For we cannot allow the use of chemical weapons to be normalised - either within Syria, on the streets of the UK or elsewhere."
Inspection has 'full support' of UK
In a statement given to the OPCW, Prime Minister Theresa May had said the inspectors had the "full support" of the UK Government and that Number 10 "looked forward to their report".
"It is imperative that the Syrian Arab Republic and the Russian Federation offer the OPCW Fact Finding Mission team their full cooperation and assistance to carry out their difficult task," she adds.
The PM goes on to again condemn the "despicable and barbaric attack" in Douma on 7 April, which resulted in air strikes by the US, UK and France over the weekend.
Welcome to our live coverage of another day of heightened tensions between the UK and Russia, with the latest row sparked by allegations that Moscow is blocking inspectors from the Organisation for the Prohibition of Chemical Weapons (OPCW) from reaching the site of a chemical weapons attack in Syria.
Russia has denied the claims.
NATO Secretary General Jens Stoltenberg has defended the weekend’s airstrikes in Syria, saying the international community had to uphold the international ban on the use of chemical weapons.
Stoltenberg spoke at a joint news conference with Turkey’s foreign minister on Monday, after airstrikes by the United States, France and Britain that hit Syria.
He says Russia had “again and again” prevented an independent investigation by the U.N. and that this left “NATO allies no other alternative than to act the way they acted.”
He says the Western alliance “cannot be silent where chemical weapons are used” and that “there was more than enough reason to act and not to act would be to erode the ban on chemical weapons.”
The NATO chief is in Turkey for talks with President Recep Tayyip Erdogan and other officials.
