Military checkpoints popped up in the Gambian capital city of Banjul this week to crack down on public protests following several rallies that led to clashes with authorities and the death of opposition party members. The demonstrations kicked off this month in an effort to push for electoral reforms as the small West African country prepares to head to the polls this year, with President Yahya Jammeh up for reelection after more than 21 years in power.

Dozens of opposition leaders and activists have been arrested by the Gambian government since peaceful protests began on Thursday, April 14.

Human rights groups voiced concern on Friday over arrests in Gambia after a rare public demonstration in the West African nation, where President Yahya Jammeh has come under regular criticism for his increasingly authoritarian rule.
