US intelligence estimates that 100-150 people have died from detected chemical weapons attacks used “on a small scale” by Syrian government forces, according to a White House statement early Friday. Data are likely incomplete. There is no reliable evidence of the Syrian opposition acquiring or using chemical weapons. White House Deputy National Security Adviser Ben Rhodes said Obama had decided to provide military support for the Syrian opposition following the use of chemical weapons by the Assad government. Rhodes did not clarify whether this support entailed arms.
