A wave of deadly gun violence has struck multiple regions in recent days. In Saint Vincent and the Grenadines (a 32-island Caribbean nation popular with tourists and yachtsmen), four people were killed and four others wounded in an apparent gang attack in the Green Hill community near the capital, Kingstown, bringing the country's homicide count to 37 so far this year; police have made no arrests and are appealing to young people to reject criminal life. Separately, in Dera Ismail Khan (a city in Pakistan's northwestern Khyber Pakhtunkhwa province), a suicide bomber rammed an explosives-laden tractor trolley into the Aman Mela police checkpost, killing 12 people — including civilians and a customs official — and injuring 35 others, with two rescue workers subsequently shot dead while transporting victims from the scene; the Pakistani state has attributed the attack to the banned Tehreek-i-Taliban Pakistan, and security forces have launched a counterterrorism operation in response.
