There are a number of FDI data sources as mentioned by Md. Akhter, Martha Carro, and Joao Bento that you might retrieve. Mainly we download the data from UNCTAD and OECD. For example, the World Investment Report of UNCTAD provides annual development of FDI in many countries. For 2016 FDI UNCTAD report, you download it here: http://unctad.org/en/pages/PublicationWebflyer.aspx?publicationid=1555 or here: http://www.worldinvestmentreport.org/wir2016/
Another trusted source is OECD. FDI OECD 2016 can be accessed here: http://www.oecd.org/corporate/FDI-in-Figures-April-2016.pdf
I hope this link will be useful: MENA-OECD Investment Programme
Draft Background Note:Recent FDI Trends in the MENA Region, https://www.oecd.org/mena/competitiveness/Draft%20Note_FDI%20trends%20in%20MENA_Dec.%202014.pdf.
Thank you all for the responses. I think that UNCTAD is better as far as the bilateral FDI flows http://unctad.org/en/Pages/DIAE/FDI%20Statistics/FDI-Statistics-Bilateral.aspx
