This weed is annual herb appears in winter season (November to march), leaves needle like, fleshy, flower colour white.
Dr. Mahoney can you send me the photos Galium or Mollugo because these species do not match to my specimen.
The whorled leaves in your picture made me think that it could be a Galium or a Mollugo. Here are descriptions and pictures of various Galium species:

Here is an example of a Mollugo species

Thank you Dr. Kris for your help!
I have checked all the specimens no match with mine.
Actually in my specimen the leaves are round, cylindrical shape and fleshy (like Portulaca grandiflora) not flat as in case of Galium and Molluco.
It looks like corn spurry to me. (Spergula arvensis L.). It is a fairly common weed in the United States and has been recently identified in Alaska.
Can you send a photo of the flower, because it look like Spergula
Though picture is not quiet clear, the photo appears to a sedge contrary to many suggestions from colleagues. The genus could be Cyperus, in the family CYPERACEAE. I may be wrong or correct.
I agree with Steven S. Seefeldt and Cid Aguilar. It seems to be Spergula (probably Spergula arvensis L.).
Thank you very much Dr. Steven, Cid, Sheku and Beata for your valuable answers.
Yes! it looks like Spergula arvensis and I think it is the same but if anybody is able to provide me pictures of other species of Spergula that will help me a lot.
This is definitey spergula arvensis, which is very common weed in indo-gangetic plains in India in rabi season (winter season) in most of the field crops.
This is definitely Spergula arvensis L. having black seeds that of the size of mustard. Seeds are disseminated mostly by water.
Its Spergula arvensis belonging to Caryophyllace family. Commonly known as Corn spurry or wild coriander.
