"We must now review whether in the future we should take a more critical stance” on selling arms to Saudi Arabia, Gabriel, who is also Germany's economy minister, said on Monday.
Germany's opposition Greens and Left parties demanded that Berlin halt all military supplies to Saudi Arabia, which reached $226 million in 2014.
On Saturday, Saudi Arabia executed prominent Shia cleric Sheikh Nimr al-Nimr, a senior opposition figure, and 46 others on charges of “undermining the national security” of the kingdom.
Hours later Iranian protesters stormed the Saudi embassy in Tehran as Shiite Muslims in Iraq, Yemen, Lebanon and Bahrain angrily condemned the executions.
The move was condemned as a violation of human rights across the globe.
