MR GLEN tells us 'we must take a stand against use of chemical weapons' ('View from the Commons', 19 April).

He supported the prime minister's decision to take selective military action against Syria two weeks ago.

The decision was taken because, it was claimed, president Assad had crossed a 'red line' by using these abhorrent weapons.

This however, is not the first or even the second time he has used these weapons.

There is credible evidence from a range of aid organisations working in the country that he has used them on over 200 occasions and 174 times since the first time Syria was bombed.

It is reported that they are used two or three times a month as a means to instil terror in the populace.

This means that there has been ample time over the last few years to debate this issue in parliament.

In other words there have been scores of red lines crossed.

The action taken in Syria is in marked contrast with the inaction in Yemen.

Thousands of men, women and children have died there as a result of the Saudi bombing campaign.

Many more thousands have been injured, including by cluster weapons we supplied prior to the ban.

Aid is blocked from entering the country and cholera is rampant.

In this case, the UK is an enthusiastic seller of arms to the Saudis, amounting to £4.6bn since March 2015, despite Saudi Arabia's infringement of international human rights laws.

Yet Prince Salman was welcomed here in March by the Government and had an audience with the Queen.

It is inconsistent for the government and Mr Glen to justify military action on the spurious grounds of crossing a red line, yet remain silent over the awful carnage going on in Yemen with our active support.
