Pakistan and Afghanistan have traded attacks in a dramatic escalation of tensions between the countries. Pakistan's Defense Minister Khawaja Mohammad Asif said Friday the two countries are now in "open war." Afghanistan launched a cross-border attack on Pakistan late Thursday, saying it was in retaliation for earlier Pakistani airstrikes. Pakistan then carried out airstrikes in Kabul and two other Afghan provinces Friday. Tensions have been high between the neighbors for months. Pakistan accuses Afghanistan's Taliban government of harboring militant groups that then stage attacks across the border and also of allying with its archrival India. A ceasefire ended intense fighting in October, although the two sides have occasionally traded fire since then.

Pakistani officials say a suicide bomber targeted a Shiite mosque on the outskirts of Islamabad during Friday prayers, killing 31 people and wounding at least 169 others. It was a rare attack in the capital of Pakistan as its Western-allied government struggles to rein in a surge in militant attacks across the country. Some of the wounded in the attack on the sprawling mosque of Khadija Al-Kubra were reported to be in critical condition. Television footage and social media images showed police and residents transporting the wounded to nearby hospitals. No group immediately claimed responsibility for the attack. Militant groups across Pakistan often target security forces and civilians.

A powerful 6.3 magnitude earthquake has shaken northern Afghanistan, killing at least 20 people and injuring more than 640 others. The quake struck before dawn on Monday, damaging the historic Blue Mosque in Mazar-e-Sharif. In the town of Khulm, near the epicenter, residents have been digging through the rubble of collapsed homes. The impoverished country often struggles to respond to natural disasters, especially in remote regions. The Ministry of Defense announced that rescue and emergency teams have reached the affected areas. The United Nations in Afghanistan said its teams are on the ground assessing needs and delivering urgent aid.
