Razanasoa Edmondine still looks shell-shocked as she recalls the death of her one-month-old grandson, killed by police tear gas in protests that have rocked Madagascar over the last two weeks. It was just a normal Friday. My daughter-in-law was going to the market with the baby when they encountered demonstrators on the road, she tells the BBC at the family's home on the northern outskirts of the capital, Antananarivo. Not long after, police showed up and started dispersing the protest with tear gas. It was the second day of youth-led protests, triggered by anger over persistent power and water shortages, and Ms. Edmondine's daughter-in-law ran into a nearby building with others to take cover. Police then fired more tear gas canisters into the building, quickly filling it with choking smoke. With the streets in chaos, they could not get to a hospital until the following day. By then, the damage had been done. The baby was trying to cry but no sound came out, says Ms. Edmondine softly. It was like something was blocking his chest. The doctor told us he had inhaled too much smoke. A couple of days later, he passed away. Her grandchild is one of at least 22 people the UN says were killed during clashes between police and demonstrators during the protests. These protests have escalated into broader dissatisfaction over corruption, high unemployment, and the cost of living in one of the world's poorest nations. The situation has led to increasing calls for the resignation of President Andry Rajoelina, as the youth of Madagascar demand action against the chronic socio-economic issues affecting their lives.
