A photograph of U.S. President Barack Obama's half-brother Malik wearing a kaffiyeh (Palestinian scarf) with Hamas slogans in 2010 was discovered Thursday, Britain's Daily Mail reported.

The slogans on the kaffiyeh read: "Jerusalem is ours – we are coming" and "From the river to the sea."

The photograph was taken at a conference Malik Obama attended in Yemen in 2010, and appears on the website of the Barack H. Obama Foundation, an organization he founded and directs that takes its name from his father.

Obama also serves as the executive secretary of the Islamic Da'wa Organization, a group created by the government of Sudan
