Human rights defenders on Tuesday decried Saudi-led airstrikes that killed at least 20 people in Yemen\u0026#039;s capital city of Sanaa, the U.S.-backed coalition\u0026#039;s deadliest attacks since 2019.\r\n\r\n\u0022The increase in fighting in Yemen is having a deadly impact and once again it is civilians that are paying the price.\u0022\r\n\r\nReuters reports civilians were killed when warplanes bombed the home of Abdullah Qassim al-Junaid, the former head of the Houthis\u0026#039; aviation college. Al-Junaid, his wife and son, and other relatives died in the attack, according to local residents and medical sources.\r\n\r\nMuhsin Sidiqquey, Oxfam\u0026#039;s country director in Yemen, said in a statement that \u0022the increase in fighting in Yemen is having a deadly impact and once again it is civilians that are paying the price.\u0022\r\n\r\n\u0022The people of Yemen have been caught in the crossfire of this violent conflict for nearly seven years,\u0022 he continued. \u0022They can\u0026#039;t wait any longer for peace―the international community must urgently negotiate an immediate cessation in hostilities and a lasting end to the conflict.\u0022\r\n\r\nSidiqquey added that \u0022all parties to the conflict must respect international humanitarian and human rights law and ensure the safety and protection of civilians.\u0022\r\n\r\n\r\n\r\nRavina Shamdasani, spokesperson for the United Nations High Commissioner for Human Rights Michelle Bachelet, said she was \u0022deeply concerned\u0022 by the \u0022continuing escalation\u0022 in Yemen.\r\n\r\n\u0022We call on all parties to\r\n\r\nReuters reports civilians were killed when Saudi warplanes bombed the home of Abdullah Qassim al-Junaid, the former head of the Houthi rebels\u0026#039; aviation college. Al-Junaid, his wife and son, and other relatives died in the attack, according to local residents and medical sources.\r\nMuhsin Sidiqquey, Oxfam\u0026#039;s ensure the protection of civilians and civilian objects, in line with their obligations under international law,\u0022 Shamdasani said in a statement. \u0022Any attack, including airstrikes should fully respect the principles of distinction, proportionality, and precautions in attack. In particular, parties to the conflict must take all feasible measures to verify that targets are indeed military objectives and suspend an attack if it becomes apparent that the target is not a military objective or that the attack would be disproportionate.\u0022\r\n\r\n\u0022Failure to respect the principles of distinction and proportionality could amount to war crimes,\u0022 she added.\r\n\r\nThe Saudi airstrikes came in response to a Monday drone and missile attack claimed by the Houthis that hit two sites in the United Arab Emirates (UAE) capital of Abu Dhabi. The attack ignited a fuel tank blast at a state-owned facility, killing three migrant workers—two Indians and a Pakistani—and wounding six others.\r\n\r\nUnited Nations Secretary-General António Guterres on Monday condemned the Houthi attack, asserting \u0022there is no military solution to the conflict in Yemen.\u0022\r\n\r\nThe UAE is a member of the U.S.-backed Saudi-led coalition that is supporting the Yemeni government in its war against the Iran-linked Houthi rebels.\r\n\r\nSince intervening in Yemen\u0026#039;s civil war in 2015, the coalition has carried out more than 24,000 airstrikes, according to the Yemen Data Project, often with U.S.-made warplanes and bombs. The group says the coalition strikes— one-third of which have hit non-military sites including schools, factories, and hospitals—have killed or wounded more than 17,700 civilians.\r\n\r\nAdvocates point to a surge in both Saudi airstrikes and civilian casualties since the United Nations Human Rights Council ended its probe of war crimes committed by all sides in Yemen last October.\r\n\r\n\r\n\r\nAccording to the Civilian Impact Monitoring Project, 29 civilians including three children were killed, and another 23 injured, last week alone.\r\n\r\nLast November, the United Nations Development Program said that the more than seven-year civil war would claim 377,000 Yemeni lives from direct and indirect causes by the end of 2021. More than four million Yemenis have been displaced by the conflict, and millions more face starvation.
